Section 3 UUPlus Codan Client and Server User Interface.

The UUPlus Codan Client and Server user interfaces consists of a number windows:

• The Console. The main user interface.• The Dialer. The mail and file transport agent.• The Mail Router. Optional, displays mail routing, POP/ SMTP sessions in real time.• The Setup Editor. A tabbed window for all configuration settings.• The Mailer. Provided for those who have fairly simple email needs.• The Log Viewer. For viewing the accounting and debugging logs• The Mail Queue Viewer. For viewing outbound mail queues.

This section discusses the console, dialer and router windows in detail. Setup, the mailer, log andqueue viewers are discussed in separate sections.

• The Server Console.

The console provides access to all the features of UUPlus Codan Server. The button bar includesa Call / Mail button, a selected item field, Send File, Logs, Queue, and Setup buttons, andoptionally includes a list of users configured on your site.

[UUPlus Codan Server Console]

• Call / Mail Button.

The function of the Call / Mail button changes with the selected item in the Sites / Users list. If"internet" or your mail server site is selected, a connection to your ISP, corporate mail server,or up-stream mail server can be started.

Clicking the Call button or double clicking on the item in the Site/Users list will initiate the call.Note that in Answer mode Codan Server may take several seconds for the call to begin.

If a user is selected and the user does not have a station ID, a Mail button will appear andthe selected user will be displayed to the right of the button. Clicking the Mail button ordouble clicking on the user in the Sites/Users list will bring up UUPlus' console mailer. IfPassword Protection is set you will be prompted for a password.

If the selected user has a Station ID, rather than bringing up the mailer, Codan Server will callthe user. Note that the user must be set to answer inbound calls.

• Send File.

Codan Server provides the ability to send a file directly to a remote site. Select the user tosend to and click [Send File] or drag and drop the file onto the console.

• Logs.

Clicking the Logs button will bring up the Log viewer. The log viewer lists all of the UUPluslogs detailing all the actions of all UUPlus functions.

• Queue.

Clicking the [Queue] button will bring up the outbound message queues for remote users andyour mail server.

• Setup.

Clicking the [Setup] button will bring up the Codan Server configuration editor.

• Site / User List.

This is the list of your mail server and the users set up on your system. Select an item andright-click for options, or double-click to call or bring up the mailer. Clicking on the list title barwill refresh the message, size, and last accessed data. This list is updated automatically oncea minute.

• Pop-up Menus

Right-Clicking on the Sites / Users list will bring up a menu with a number of options andfunctions.

• Reset. Restarts all processes. Click if you need to restart all the processes in UUPlus.• Debug Mode. Sets verbose logging mode for trouble shooting. This effects POP/SMTP

connections, mail routing, and the dialer in call-only systems. Due to the size of the logsyou do not want to normally run in debug modem.

• Help. Context sensitive help. Same as pressing F1.• Application Note. Displays this manual.• Setup. Brings up the Codan Server configuration editor.• Refresh Display. Updates the Site/ User display.• Show Mail / Msgs To: (selected user / site). Brings up either the mailer or the outbound

queue viewer for the selected user or mail server.• Close to Tray. When checked, clicking the [X] in the upper right-hand corner of the

console window closes to the tray rather than exiting, leaving Codan Server running inmemory. This prevents the inadvertent shutdown of the mail server.

• Show Grid Lines. Toggles the grid display in the Site / User list.• Increase / Decrease Font. Changes the font size in the console Sites / Users list.• About UUPlus Codan. Displays the Version Number and License information.• Exit UUPlus. Does just that. Use this to exit when Close to Tray is checked.

• The Client Console.

The Client console is very much like the Server console except that it is limited to the mail server,the user, and a the anonymous file transfer feature.

[UUPlus Codan Client Console]

• Call / Mail Button.

The function of the Call / Mail button changes with the selected item in the list.

To make a call to your mail server, select your mail server in the list (this is always the firstitem) and then click the call button. You can also double click the item in the list to initiate thecall. Note that in Answer mode Codan Client may take several seconds for the call to begin.

• The Dialer.

The dialer is a transport agent that transmits data from one location to the next. An errorcorrecting, sliding window, latency tolerant serial protocol is used.

[UUPlus Codan Answer Mode Dialer]

The dialer has a number of options depending on the version.

• Reset/Stop Button. When a call is active there is a [Stop] button. Clicking the Stop buttonwill try to end the session gracefully and shut down the modem. Should there be a problemshutting down the session, a second click will end the program forcibly.

When idle, there will be a [Reset] button. Clicking notifies Codan Server that the dialer isgoing to exit and wishes to be restarted.

A right click will afford the following options:

• Answer Enabled. Answering inbound calls can be temporally turned off. This is helpfulwith Codan modems and you need to make a voice call. Available only in Answer mode.

• Debug Mode. If checked, the log will display a fairly detailed account of the call. Readingand understanding this log is really intended for UUPlus tech support, but it is good fortrouble shooting a modem init string. Normally you should not have this checked.Available only in Answer mode.

• Test Mode. Displays a command line to send commands directly to the modem and avery high level of debug information. Available only in Answer mode.

• Wide Display. Set to suit your preference.• Display Log. Allows turning off the real-time log display. Though watching a UUPlus

connection may prove to be more entertaining than the programming on your local TVstation, you have the option of not displaying the log.

• Exit. Closes the dialer without notifying Codan Server to restart it.

Note that Debug and Test modes in the call mode dialer are set from the Client console.

• The Mail Router.

The mail router is usually a behind the screens type of program, but again, due to the lack ofgood television programming (or well written mail server manuals) we found it interesting towatch. The mail router window is displayed when you either:

• Check the Show Mail Server box in Setup. • Right-click on the console and check Debug Mode.• Right-click on the console and click “Test Mail Routing”.

[UUPlus Mail Router]

The above diagram shows the router in normal mode. Note that mail routing, POP, and SMTPsessions will be displayed in real mode. If you put UUPlus in debug mode and expand the

Page: 10


window so you can read it, this feature can be very helpful to quickly diagnose a routing, POP orSMTP problem.

[UUPlus Mail Router in Test Mode]

The above digram show the router in test mail routing mode. Enter an address into the To:address box and click [Test]. The destination of a message to the address will be displayed. Thisis very helpful in determining the best settings to use on the routes tab and allows you to design amail routing architecture for your system without risking sending annoying test messages.

Note that this feature does not send any messages, it only simulates how a message will berouted.

• Accessing Mail, Codan Server.

Mail can be accessed by calling in, popped over a local area network or directly from CodanServer console using UUPlus’ mailer.

• UUPlus Console Mailer.

If the user is local or calls directly into the Codan Server server, double-clicking on a user inthe console Site / User list brings up the UUPlus mailer for the selected user. If passwordprotection is enabled you will need to know the user's or the postmaster's password.

• Local Area Network (LAN).

Codan Server includes POP and SMTP servers which allows users access to their mailboxover a LAN using a POP3 compatible mailers such as Eudora, Outlook, Outlook Express,and Pegasus Mail. Mail can also be accessed from a mailer running on the same computeras Codan Server. Use the static IP address of the Codan Server computer in the mail serverfields of the mailer.

• Accessing Mail, Codan Client.

• UUPlus Console Mailer.

Mail can be read using the console mailer by selecting the user in the console list andclicking the Mail button or double-clicking on the user. If password protection is enabled youwill need to know the user's or the postmaster's password. Note that this is more an"administrators" mailer so it lacks many of the features of a full-featured mailer.

• POP3 Mailer.

Codan Client includes a POP and SMTP server which allows access to mail using POP3compatible mailers such as Eudora, Outlook, Outlook Express, and Pegasus Mail. The mailermust be running on the same computer as Codan Client.

Section 4 Codan Server Configuration

This section is broken down by the tabs in UUPlus Codan Server Setup.

• Settings Tab

The Station Settings tab contains the basic information about the site, display options, securityoptions, and the unknown local mail routing options.

[Setup Settings Tab]

• Answer Calls.

Check this option to answer inbound calls.

• Station ID.

The is your station ID or address that identifies you on the HF network.

• Smart Host.

A “smarthost” is simply a mail server that knows what to do with any given email address.Your “smarthost” is the site that you receive your Internet mail from and send Internet mail to.This is either an Internet service provider (ISP), a corporate mail sever, or a up-streamUUPlus SOHO Pro Server site.

If your mail server is an ISP or corporate, select "ISP". If you wish to specify a UUPlus SOHOPro server, select "UUPlus Site" in the drop down box and enter in the details for connectingto the SOHO server.

If you are running a "captive" network, that is, you don't connect to the Internet or other mailserver, select "none" in the drop down box and use the ".uucp" domain extension (see FullInternet Name).

Examples: ISP tree none

• UUPlus Site Name.

The “UUPlus Site Name” is the name other sites know you by. It is usually sent as your loginwhen calling and you usually send it when a site calls you. A sitename should be from 3 to 12characters in length and can contain only alpha-numerics and a single underscore (_) ordash (-). Dots and spaces are not permitted.

For UUPlus Codan Servers, this will usually be the first part of your Internet Name. Forexample, if your Internet Name (FQDN) is "tree.ext", your UUPlus name is "tree".

Example: tree

Page: 12


• Full Internet Name.

This is the Fully Qualified Domain Name (FQDN) of your site. The FQDN is the textrepresentation of one or more static IP address on which a mail server resides on theInternet.

Example: tree.ext

If you are running a "captive" network, that is, you don't connect to the Internet or other mailserver, use the ".uucp" domain extension.

Example: privatenet.uucp

• Enable POP / SMTP Servers.

On some systems you may not want to run UUPlus’ POP and SMTP servers, such a whenyou are using UUPlus only for HF connections and are co-locating it on a network orcomputer that is running another email server for handling local POP/SMTP.

• POP / SMTP Ports.

UUPlus allows you the flexibility to change the IP port numbers from the standard POP andSMTP ports. Setting a port to “0” will disable the service. If you need the SMTP service tohandle inbound mail but don't need the POP server, set the POP Port to 0.

• Product Key.

Click to change the UUPlus Codan Server product key.

• Show Site / User Status.

This is the site / user list in the Codan Server console window, which lists the sites and users,the number of messages, mailbox/queue size, and the time elapsed since last accessed. Forsecurity reasons you may wish to hide this window. If your users will be accessing their maildirectly from the Codan Server software with the Console Mailer, this needs to be checked.

• Show Mail Router.

If checked the mail router will be displayed. This options provides a real-time log of mailrouting and the POP/SMTP servers.

• Load UUPlus at Startup.

When checked UUPlus will load when the computer is booted and logged into. Note thatUUPlus does not run as a service, but as an application, so the computer must be logged intoby a user for UUPlus to start. This is usually not a problem on today’s computers as they willnot boot without user intervention after a power outage.

• Enable Password Protection.

If checked, the postmaster's password will be needed to view the logs, queue, or enter theSetup screen. Accessing mail will also require the user's password.

• Unknown Local Mail To.

In most mail systems mail to unknown users is returned to the sender, or “bounced”.Because UUPlus is often used where this might not be desirable, UUPlus gives you anumber of options.

• Delete. The message is deleted and the action is noted in the logs.• Return. The message is returned to the sender.• Forward to Postmaster. The message is placed in the postmaster’s mailbox.• Forward to Smarthost. The message is sent to the smarthost. Note that this assumes

that unknown mail can not be delivered to your site by the smarthost and they will know

Page: 13


what to do with the address.

• Users TabA “user” is generally defined as one person who connects in some way, shape, or form to a mailserver. A user can be local, that is, they connect to the mail server via a LAN, or they can be“remote” where they connect to the server by HF.

[Setup Users Tab]

• User IDs.

Click to view the serial numbers of the Codan Clients that are connecting to your server.

• Postmaster.

Use the drop-down list to select the user designated as the site postmaster.

• Adding / Removing Users.

To add a new user click the [Add User] button. The fields for the user will be set blank so youcan enter the new username password, and their station ID if you will be calling them. Seethe User Name section below for restrictions for usernames.

If your smarthost is “ISP” and you are fetching your users, it is recommended that you usethe same username and password as on the server you are fetching from. This will greatlysimplify things.

If you have entered the maximum number of users and sites permitted by the registrationkey(s) the [Add User] button will be disabled.

To remove a user click the [Remove User] button. Note that all configuration and mail fileswill be deleted for this user with the exception of the user's mail Archive if mail archiving isenabled.

• Import List.

Use the [Import List] button to import or export the list of users. This is a comma separatedtext file in the format:

username, password

No other fields are permitted and spaces will be removed.

• User Name.

Users are assigned a “username” which can contain the letters A-Z, a-z, the numbers 0-9, adot (.), a dash (-), or an underscore (_). Usernames should be from 2 to 16 characters inlength and are not case sensitive.

Page: 14


Usernames can be of any convention, though “firstname.lastname” or using the first initialand the last name are common.

• Password.

Each user is assigned a password. Passwords should be easy for the user to remember, butdifficult to guess. A combination of upper and lower case letters with a number or two arerecommended. Any keyboard text character can be used with the exception of the spacecharacter.

If the user is connecting with UUPlus Personal Pro they can remotely change this value.

• Size Limit.

If you wish to restrict the message size sent to this user you can set the value here.

• Station ID.

Enter the user’s station address only if you will be calling them.

• Schedule Call.

Click the [Schedule Call] button to schedule calls to this user. See the section on the Callingtab for more information.

• Fetching.

Click to add a fetch for the selected user. This assumes the user's fetch login and passwordis the same as needed for the fetch, and the mail server field is filled in with the SMTP Serveraddress on the ISP Settings tab. You are presented with a edit box so you can make anychanges needed. See the next section for details on each of the settings.

• Send Attachments Separately.

As mentioned previously, users can either access their mail locally by POPing over a LAN,using the console mail reader, or they can call in from a remote location with UUPlusPersonal. The only difference between “local” and “remote” users is how mail attachmentsare stored in their mail directory.

If the user is local, that is they always connect by POPing their mail or with the consolemailer, un-check Send Attachments Separately. Attachments will be left internal in themessage in their normal MIME format. This is preferred for POP users, and mandatory forconsole users.

If the user is remotely connecting with Codan Client, this option should be checked.Attachments will be removed from the message, converted to their native format, thencompressed for transfer. This can cut connect times by as much as 80% when compared toleaving the attachment internal in the message. Note that even though attachments areseparated, the user can still POP their mail as the attachment is placed back in the messagewhen it is POPed.

• Clear User ID.

When a user calls in with the Codan Client software the serial number of the client is sent tothe Codan Server. The Server keeps track of each user's serial number and if another usertries using the same serial number the second user is not permitted to login. This is to insurethat all Clients have a valid software license.When you are first setting up and testing your system often a Client software key gets usedfor a test user and then later for a legitimate user. Often the system administrator hasn'tdeleted the test user, and might want to keep using the test account for just that, testing.When the Clear User ID button is clicked the listing for the user and their associated serialnumber is removed from the User ID list.We figure that clicking this button on a daily+ basis will encourage everyone to purchase

Page: 15


enough Client licenses for all their users.

• ISP Settings TabIf your smarthost is set to “ISP” the ISP settings tab will be visible, it is hidden when yoursmarthost is a UUPlus site. Your smarthost will be “ISP” if you receive your Internet mail from andsend outbound mail to an Internet ISP or corporate mail sever.

[Setup ISP Settings Tab]

• Connection Via:

Select "LAN" or one of the Windows Dial-up Networking entries when fetching mail from anISP or corporate mail server over a PSTN, MPDS, or any other Windows Dial-up Networkingconnection. If you are fetching from a corporate mail server over a LAN or other full timeconnection, select LAN.

When using a Dial-up Networking, you can select the connection you wish to use in the drop-down box. Note that you must already have a dial-up account configured in Windows beforeyou can set this. The [Edit Entry] button provides to access the settings for the selectedentry. The [Settings] button will display a setting window to override the settings in WindowsDial-up Networking.

If a Dial-up Networking session is already active, the active session will be used. When thefetch is complete, the connection will be left in the state it was found.

[Dial-up Networking Settings]

• Phone Number.

Enter the complete phone number to dial. UUPlus uses this number rather than thenumber settings in Windows. Leave blank to use the Windows setting.

Page: 16


• Login.

Enter the login (account name) for the account. UUPlus uses this string rather than thelogin setting in Windows. Leave blank to use the Windows setting.

• Password.

Enter the password used to log in with. UUPlus uses this string rather than the passwordsetting in Windows. Leave blank to use the Windows setting.

• Keep Alive After Connect.

If checked, the connection will be left up for other processes to use.

• Force Hangup After Connect.

If checked, the connection will closed after the connect, regardless of the state before theconnection.

• Connect Every:

The frequency, in minutes, to send and check for mail. The values provide range from 10minutes to 2 hours. The connects are scheduled every ‘n’ minutes from the time you startCodan Server Pro.

A dash (-) in this field disables timed connections, and enables the Scheduled Call button toschedule connections at specified times and days of the week. The button is provided herefor easy configuration of ISP call events. See the Events Tab section for more information.

• Immediate Send.

If Immediate send is checked, outbound mail will go immediately rather than when a fetch isscheduled. Do not check this when you are using a dial-up connection.

• Schedule Call.

Click to set up a calling event for the Fetcher. This option will not be available if ConnectEvery is set. See the Events Tab section for more information.

• Default Server:

Enter the address of the default mail server to forward outbound mail to. This can be in eitherdot or Internet notation.

Examples: mail.isp.net 192.168.0.3

• SMTP AUTH User:

If all your mail is going out through the same server and it requires SMTP AUTH, enter thelogin (username) to use for the SMTP AUTH command. This will usually be a user on thesystem you are connecting to. In this case the UUPlus Fetcher only performs one AUTH loginper session and then sends all queued mail during the session.

Leave this field blank if the AUTH command is not needed or supported, or you are usingmultiple SMTP servers.

• Password: (for AUTH command)

The password to use for the SMTP AUTH command. This must be the AUTH User'spassword.

• SMTP ID Domain.

The SMTP ID field is used in the SMTP hand-shaking when sending a message.

If you are connecting through a local ISP to a remote mail server and are rejected because areverse DNS lookup fails due to your FQDN not being registered with your ISP, enter the

Page: 17


FQDN of the local ISP in this field.

If that is not a problem but your UUPlus Internet Name is not the same as your FQDN, enteryour FQDN in this field.

If you haven't a clue what I'm talking about, don't feel stupid. I tried to keep this simple, butSimple Mail Transport Protocol is anything but simple.

• Rewrite SMTP Mail From:<>

If your UUPlus Internet Name is not the same as your FQDN, reverse DNS lookups arefailing, and you need to have the SMTP MAIL FROM:<> field show your FQDN rather thanyour Internet Name to prevent the reverse lookup from failing, enter the full domain.

• POP Port.

The default port to connect to for POP3 connections. If the POP server you are connecting tois not using the standard port 110, change this value to the needed port.

• POPS (Check Box).

Checking POPS will set the Default POP Port to the default SMTP SSL port of 995. Un-checking POPS will set the Default POP Port to the default POP3 port of 110.

• SMTP Port.

If the SMTP server you are connecting to is not using the standard port 25 for SMTPconnections, change this value to the needed port.

• SMTPS (Check Box).

Checking SMTPS will set the SMTP Port to the default SMTP SSL port of 465. Un-checkingSMTPS will set the SMTP Port to the default SMTP port of 25.

• Fetch List.

Accounts can be fetched from any server over a dial-up or full time connections. Adding,editing and deleting fetch entries are accomplished using the provided button on the Userstab.

Rather than each item individually, you can click the [Fetch List] button to edit them in a texteditor.

[Setup, Users Settings Tab, Fetch Button]

Enter the Local User to fetch for, the Mail Server to fetch from and optionally an alternate portto use, the POP Account to fetch and the Password for the account.

The mail server can be specified in dot notation (192.168.0.2) or in Internet notation(mail.myisp.ext). If you wish to override the default POP port setting, enter the alternateport in the box following the Mail Server field (mail.myorg.ext:995).

Note that the mail server field must have one or more dots in the field, a machine name is notaccepted. Note also that using dot notation eliminates the need for a DNS lookup, thus

Page: 18


speeding up the connection. This can be a real advantage when using a dial-up account asoften the fetcher will start up the POP sessions before DNS can be activated by WindowsDial-up Networking.

A check box is provided to quickly enable/disable a fetch entry. When disabled, the settingswill be preserved.

If the account is a multi-drop mailbox (mail to more than one address placed in a single mailbox) check the Multi-Drop box and Codan Server will attempt to route the message based onthe To: and Cc: lines. If none of the addresses in a POPed message are valid local users, themessage will be placed in the postmaster’s mailbox for forwarding to the correct user. Notethat you can also enter an “alias by sender” entry to help facilitate multi-drop mail routing.

Check to send attachments separately from the message. This will greatly speed upconnections.

• Modems Tab.

All settings to control the modem are found on the Modems tab

[Setup, Modems Tab]

• Com Port.

Select the com port the modem is connected to. Only active ports are listed. If the correctport is not listed, the port must be activated before entering Setup for it to be selected.

If you are connecting with a USB / Serial Adapter, and the adapter is not plugged in, the portwill not be listed. To list the port, shutdown UUPlus, plug the USB adapter in, restart UUPlusand click Setup. The USB com port should now be listed. If it is not, you may have to rebootyour computer to get it to recognize the USB adapter.

• Login Timeout.

The length of time to wait for modem negotiation (sync) on an inbound call before giving up.This timer is set when the modem goes off hook, then it is set again when the two modemsync for the login/password exchange. If the timeout is set at 30 seconds, it will be at most 60seconds before the call attempt is abandoned.

For inbound PSTN calls, the timeout should set at 30 seconds unless it often takes more timefor the modems to sync. For inbound HF radio calls, the timeout should not be set less than120 seconds. If Codan Server seems to be hanging up a call before the two modemsnegotiate sync, increase the timeout.

• Max time.

The maximum time allowed for a answered connection. A setting of 0 will disable the timer.

• Modem:

Select the option for your modem. If you have an older 9002 that has not been upgraded (doso as soon as possible) to the current firmware, select the Older 9002 option.

The Custom option is provided just in case, but it shouldn't ever be needed.

• Init String:

The AT initialization string to initialize the modem. For the most part, you shouldn't ever needto change this from the default and it is not recommended that you do so.

Page: 20


A vertical bar (|) indicates a carriage return. Note that S0=1 is not used to answer inboundcalls and should always be set to 0.

• Mdm Hangup:

The command to go on-hook. Codan HF modems use ATH2 and check Drop DTR after ATH.

• Use Defaults.

Sets the modem to the defaults.

• Codan Channel Settings:

If the HF channel is controlled by the transceiver, then the radio determines what channel tocall / answer on. If the HF channel is controlled by UUPlus, then the software determineswhat channel to call / answer on. Enter, in order, the channels programmed on your NGT touse.

Advanced Settings Button.Clicking the Advanced Settings button will reveal several other options.

• Full Modem Reset.

Check this option if you wish the modem to be fully reset after every inbound call. If thisoption is not checked, the ATZ command will be sent to the modem. Has no effect on callonly Clients

• Reset Delay:

The amount of time the software waits for the modem to hang-up before resetting themodem. For HF modems, set the reset delay no less than 12 seconds for answer modemodems, you may need 16 or 20. For satellite, cellular, or external modems, 4 secondsis good.

• Ignore Init Err.

Check this box this box if an initialization error occurs and you wish to ignore the error.

• Slow DCD.

Some modems will momentary drop and then raise DCD even though carrier has notbeen lost. Checking Slow DCD will cause the UUPlus protocol to ignore DCD low forseveral seconds in hopes it will come back up. If it doesn't, then the connection isterminated.

• Ignore DCD.

Some modems do not report DCD high once modem sync occurs, thus when UUPlusenters the protocol phase and begins DCD checking it will erroneously report that carrieris lost. Check this box to ignore carrier detect.

Some older modem cables also do not have the DCD pin in them, you can check thisoption to overcome the missing pin.

• Ignore CTS.

Check this box to ignore Clear to Send. CTS is used to inform each modem when theycan send data. When a modem buffer is full, the modem drops CTS indicating that theremote should not send any more data until CTS is raised. Some modems (notably cellphones) do not have the CTS feature, so the modems will connect and login, but stall inthe protocol phase because they never raised CTS. If this is the case, check this option.

Some USB to Serial adapters also do not raise CTS, so checking this option allows theconnection to function normally.

Page: 21


• Flow Control.

Determines if CTS is controlled by the hardware or software. Most modems usehardware flow control.

If Hardware flow control is selected, you can choose between RTS and DTR settings.RTS is the default and most common, however, some USB/Serial adapters fail tofunction correctly with RTS selected. If the dialer receives no response from the modem(and the port setting is correct), the modem returns an error when dialing, or theconnection syncs but does not transfer data, try using the DTR setting.

The RTS and DTR setting will vary between modems, USB adapters, and computers, soexperimentation is the only way to determine the best setting for your equipment.

• Filters Tab.

UUPlus Codan Server uses several filters to cut down on spam. These are simple black lists sothey should not be used to replace more sophisticated systems designed for corporate mailservers.

Care should be given to the words and phrases entered into these lists as legitimate mail can bedeleted.

When a message is deleted it is noted in the Routed log, but neither the sender or recipient isnotified.

• Header Kill.

The kill file is used to search message headers only. Any message with a keyword or phrasefound in the header is automatically deleted. Mail from unwanted email addresses ordomains can be places in this filter. Each keyword or phrase is placed on its own line, thereare examples in the default file. If the “@” symbol is placed on a line by itself, Codan Serverwill delete all inbound mail, so be careful with this. “@spammers.com” will kill all mail fromthat domain.

• Subject Kill.

The subject kill file only searches the Subject: line in the message header. There areexamples in the default file.

• Body Kill.

The body kill file searches the first 50 lines of a message body. Spam is usually HTML

Page: 22


formatted text so the HTML formatting is removed and the result is scanned.

• Attachment Kill.

The attachment filter is used to delete any email containing an executable attachment. Emailviruses are transmitted in executable attachments. If SOHO finds an email containing anattachment with an extension in the list, the email is automatically deleted.

If you need to send an executable attachment (such as an .exe file) we recommend changingthe .exe to .~xe before sending the attachment. When the attachment arrives, change theextension back. It is better, however, to zip the file.

• Events Tab.

UUPlus Codan Server contains an event scheduler to allow for regularly scheduled calling.

[Setup, Events Tab]

• Enable/Disable.

Existing events can be quickly enabled or disabled by selecting the event and toggling theEnable/Disable button. A disabled even will have a “#” character preceding the event field.

• Add Event.

Click the [Add] to add a new event. Note that you can select an existing event, then click theAdd button and the information in the existing event will be used to set up the Add Eventscreen.

[Events Tab Add Event]

In the event add/edit screen, set the hours and minutes with the [+/-] buttons or type in thevalue. Care should be taken so that events are not scheduled so as to conflict.

The Event field is a drop-down list and will contain most of the valid events. You canschedule calling remote sites as well as enable and disable answering on the enabledmodems (this can be helpful in an HF setup to schedule times for voice calls and data calls).

Page: 23


There are also check boxes for each day of the week to schedule calling.

You can also create up to 24 events a day using the Set Every 'n' Hrs. field. Set this field to1, 2 , 4, or 6 to add 24, 12, 8, 6 or 4 calls per day. The Hour field will be set at 00 indicatingthe start hour, then set the Minute field to the number of minutes past the hour you wish tocall. Set the days to call, then click [Ok]. Up to 24 calls will be scheduled. Delete the entriesfor times you do not wish to call.

To make it easy to add calling events, “Schedule Call” buttons are located on the Call tab inSites, the ISP Settings tab, and if you are configured to use Codan modems, there will alsobe one on the Users tab.

• Edit Event.

Select the event to edit in the list and then click [Edit].

• Delete Event.

Select the event to edit in the list and then click [Delete].

Section 6 UUPlus Logs.

UUPlus records most of what it does in logs. These logs can be viewed by clicking the [Logs] buttonin the UUPlus console.

[UUPlus Log Viewer]

There are two types of logs, “record keeping” and “debugging”. The Call and Routed logs are forrecord keeping, the rest are used primarily for debugging.

Since longs can often be quite large and you may only want to see the end of the log, the viewer canbe set to read in only the last 500k or so of a log. The "Read In:" setting can be set to yourpreference. Clicking the Read In label will load the entire log, overriding the setting one time.

Entries in the logs start with a time stamp, with the exception of the Call log, which first has the linenumber followed by the time stamp. The log segments shown here have this time stamp removedwith the exception of the call log so the entries will fit on the page.

• Call Log [Calls]

UUPlus Codan Client uses a single file for all calls.

UUPlus Codan Server uses a monthly call log where the calls for each calender month areplaced in a new file each month. A drop-down list is provided to the right of the [Calls] buttonlisting the available monthly logs. Selecting a log from the list displays the log.

The call log is in the following format:line time-stamp site time sent rcvd cps sync cntmsg pkts

line. The line used in the call. In Personal and Codan Server client, the line will always be 1.

time-stamp. The month, day, hour and minute of the call.

site. The site connected to.

time. The off-hook time in seconds.

sent. The number of bytes sent in the session. Note that in the case of failed connections thisnumber is cumulative and indicates the progress for the combined connections.

rcvd. The number of bytes received in the session. Note that in the case of failed connectionsthis number is cumulative and indicates the progress for the combined failed connections.

Cps. The characters per second rate for the session.

sync. The time, in seconds, used for the modems to negotiate the connection.

[msg]. The CONNECT message, if any, received by the modem. This is primarily used byanswer sites to determine the remote modem type that called.

{#}. The maximum number of un-acknowledged packets (window size) used in the connection.

• Routed Log [Routed]

The Routed log is a summery of all messages processed, one entry per message. The entry is aduplicate of the final entry for a job in the rmail log.

The general format of the routed log is:timestamp jobname placed sender recipient length

jobname The inbound or starting job name.

placed Either “local” if the mail is placed in a local mail box, “sitename” if spooled to a UUPlussite, or “internet” if spooled to an SMTP server.

sender The address the message is from.

recipient The address or local user the message is to. If the message is to a local user, themailbox ID is included. This ID is also recorded in the POP log or if the user is remote, in the Cicolog.

length The uncompressed message size.

Examples:D03D7 local, From:[[email protected]] To:[user1:D03D7] Len: 8118D0193 uuplus, From:[[email protected]] To:[[email protected]] Len: 1068D0015 internet, From:[[email protected]] To:[[email protected]] Len: 13407

If you have any entries in the Inbound Mail Filter file there will also be entries like this:Kill: To: [email protected] From: [email protected] Found:[spammer.org]

• Rmail Log [Rmail]

The Rmail log records in some detail how mail is processed and routed. There are severalprocesses associated with mail routing, such as “uuxqt”, which is the process that readscommands from a remote system and executes them. “uzip” is the un-zipping process, “ubat” un-batches the file into individual messages, and “mail” (actually “rmail”, for “route mail”) is theprocess that determines where to copy a message to, either to a local mail folder, spooled to aUUPlus (UUCP) site, or placed in the outbound mqueue (mail queue) directory for delivery viaSMTP.

The general format of the rmail log is:timestamp process jobname [information][action taken]

Note that the job name, sometimes referred to as the message ID, corresponds to the file nameof the message or batch file. This does not necessarily have any relationship to the message IDlisted in the header of a mail message. UUPlus uses a sequenced 4 digit hexadecimal number inthe range of 0001 to FFFF, proceeded by a “D” character, for file names to insure that no two willever be the same (unless you keep some 65,000 messages in a single directory…)

The following log segment shows processing an inbound mail batch from another UUPlus site, inthis case the site name is “uuplus”.

-- Rmail started --UXQT -- uuplusUXQT D06B4 bMail, Msgs: 4UZIP D06B4 (19811 -> 66721) 70%UBAT D06B4 From:[Full Name <[email protected]>] To:[user1]MAIL D03CE local, From:[[email protected]] To:[user1:D03CE] Len: 41941UBAT D06B4 From:["Full Name" <[email protected]>] To:[user1]MAIL D03CF local, From:[[email protected]] To:[jhb:D03CF] Len: 7335UBAT D06B4 From:["Full Name" <[email protected]>] To:[user1]

The next log segment shows processing a locally generated message being added to a batch fileto be sent to another UUPlus site, in this case the site name is “uuplus”.

MQUE --MQUE D0192 From:[[email protected]] To:[[email protected]]MAIL D01F2 BCHD uuplus, From:[[email protected]] To:[[email protected]] Len: 6380

Following are some of the error and informational messages and an explanation of what causedthem.

MAIL ERROR: (L) Could not copy attachment: [input filename] to [output filename]MAIL Attachment not included: d:\uuplus\spool\attach\A.uuplusF0030

The above is caused when a message arrives without it's attachment it is generally caused by thecall being cut off after the mail batch was received but before the attachment was fully received.In this case the attachment will be sent later when all of it arrives.

ZIP: ERROR Could not zip: d:\uuplus\spool\attach\SUNDAY

The mostly likely cause of the above is that the mailer (and perhaps the user that was running themailer) did something unanticipated when composing the message and the attachment wascorrupted, or not even included, when the original message was sent.

ATCH Decode: file not encoded: d:\uuplus\spool\attach\A.sitenameF4656ATCH Could not Decode: d:\uuplus\spool\attach\A.sitenameF4656

The above was caused by a malformed email attachment. When the sender forwarded themessage, the mailer they were using used the wrong MIME format to include the message,rendering it unreadable before it ever left their computer.

• POP Server Log [PopSrv]

The POP server log shows the actions of the POP server. You will normally only need to view thelog to trouble shoot a POP connection or if you think a message disappeared and you are tryingto find out what happened to it.

The session, action, message number, sender, length, and message ID are recorded in thelog. Note that the ID indicated in this log corresponds to the message ID that follows theusername in the routed log.

POP3 [uuplus.com] listening on port 110--0) Connection request from jhb [127.0.0.1]0) Sent msg[1] From:[Full Name <[email protected]>] Len:[51592] ID:[D031F]0) Sent msg[2] From:["Full Name" <[email protected]>] Len:[2221] ID:[D0320]0) Disconnected.

Most of the error messages in the POP log are beyond the scope of this manual and should bereferred to UUPlus tech support of you don't understand them. The following message, however,should be self-explanatory.

Please close all UUPlus programs restart UUPlus. If the problem persists there may beanother program preventing UUPlus from working correctly which will need to be turnedoff, or TCP/IP may be incorrectly configured or not installed.

Sometimes certain mailers seem to loose messages. If this seems to be the case, the POP logshows definitively if the message was delivered to the mailer or not, and if it was, the message issomewhere in the mailer. Note that the most common cause for loss of messages in a POPsession is that the user has neglected to move messages from the inbox to another folder andoften has hundreds of messages in their inbox, only 6 to 10 or so are visible at any one time.

• SMTP Server Log [SmtpSrv]

The SMTP server log shows all inbound messages received via SMTP. The general format of theSMTP log is:

timestamp session address action [jobname len sender recipient]

session. Indicates which one of any concurrent sessions the log entry is for.

address. The IP address of the remote client.

action. The action being logged

jobname. The message ID for this message. There will be a match for a MQUE job in the rmaillog.

len. The length of the message as received.

sender. The sender as listed in the SMTP header envelope.

recipient. The recipient as listed in the SMTP envelope.

Example:SMTP [uuplus.com] listening on port: 250) [127.0.0.1] Accepted, relay OK.0) [127.0.0.1] Rcvd: D0168, len: 3176, FROM:<[email protected]> TO:<[email protected]>

• Events Log [Events]

The events log lists calling activity as well as other information important for certain aspects ofdebugging. Under certain circumstances UUPlus tech support may request this information todetermine the cause of a problem. The information is not normally needed by the end user.

Sample entries:-- Load Cron Events --Cron start cico1 HF PID: 840Cron restart: cico1 PID: 1312Cron kill 1 PID: 1312Call Line1 CICO uuplus @ 1001Calling: uuplus @ 1.[auto] [TCS], PID: 1008Calling: uuplus @ 64.4.141.247 [VPN], PID: 1708Shutdown...

• Cico Logs [Cico 1]

“Cico”, which stands for Copy In, Copy Out, is the program that transfers the mail to and fromyour system. It is basically a file copy mechanism designed for satellite phones, HF modems, orany either slow, error prone, or expensive connection. Cico also handles the modemconfiguration and dialing.

There will also be a number of error messages regarding modem init, login, and accountauthentication. They are as follows:

Modem Command Timeout. Check modem / modem configuration.

The modem is not plugged in or not turned on.Login Timer Expired. Call canceled.

The remote never answered. There could be a variety of reasons for this, from a modemerror that the modem didn't report (such as no dial tone), no circuits available (effectsland line, cell phone and satellite phones), the call didn't go through, the remote didn'tpick up, the modems didn't sync, or any number of other reasons. This error triggers a re-dial.

Error: NO DIAL TONE. Please check modem.

Plug the modem in.Warning: Comport not enabled or not found.

You have the wrong comport selected in the modems tab. This is most often caused bynot plugging the USP/Serial adapter in before making the call.

Modem ERROR: [ERROR] Please check modem INIT string.

One or more of the AT commands sent to the modem caused an error.

If you are running Win2000 Pro on a Dell laptop and are using an Iridium phone youmight get this error, if this is the case, in the Modem configuration tab, check “Ignore InitErr.”

In most other cases you should set debug on, click the Call button, and go over themodem response entries to determine the bad init command.

Section 7 Setting up Mailers for use with UUPlusUUPlus Codan Client software includes POP/SMTP servers allowing any POP/SMTP mailer tocommunicate directly with Codan Client. Codan Client acts as a mail server, allowing you to use yourmailer the same way your would while connected through your standard ISP.

• Outlook and Outlook Express.

Microsoft Outlook and Outlook Express are widely used mailers, Outlook Express is usually pre-installed on most Windows computers. The configuration process is similar for both and forsimplicity we refer to both as “Outlook".

1. Open Outlook Express.

2. On the menu bar, select [Tools — Accounts].

3. The Internet Accounts window will appear. Click the [Add] button and select [Mail].

4. Type in your name and click [Next]. This name is what will appear next to your emailaddress in the header.

5. Select “I already have an email address” and enter your UUPlus email address. Click[Next] when finished.

6. Select “POP3” as your incoming mail server.

7. Enter “localhost” for your Incoming and Outgoing mail servers and click [Next].

8. Enter your UUPlus account name (username) and password. The password is case-sensitive. Check the “Remember Password” box and click [Next]. Do not check the box for“Secure Password Authentication.”

9. In Outlook, you will be asked how you are going to connect to the Internet, select“Connect using my local area network” and click [Next].

10.You are now done configuring Outlook Express. Click [Finish] to save the configuration.

11.Assuming there is no need for any trouble-shooting, you can now send and receive youremail to and from UUPlus Personal Pro.

To test sending and receiving mail, make sure UUPlus is running and it's log window is displayed.It is also helpful to size UUPlus and Outlook so you can see UUPlus' log and Outlook at the sametime,

1. On Outlook, on the main window, click the [New Message] button to create a testmessage, address it to your UUPlus address.

2. When finished with the test message, click [Send].

3. If the email “disappears”, is not listed in Outlook's Outbox, and UUPlus' log indicates itreceived and processed a message, then sending works.

4. On the main Outlook window, on the file menu select [Tools — Send and Receive —Localhost (or the account name for the UUPlus server)].

5. This should activate a POP session. Any mail in the UUPlus Personal Pro mailbox (if yousent a message to yourself there should be at least one) should appear in the OutlookInbox. The process should take less then a second (unless there is a large quantity ofmail). If UUPlus Personal Pro is configured to call on mail check, it might automaticallybegin calling or request you to make a call. If that happens, it means Outlook iscommunicating to the POP server. You should also see some activity in UUPlus' logwindow.

Troubleshooting Outlook.

• If the Windows Dial-up Connection window comes up, requesting to dial a phone number,then Outlook is under the impression that it is supposed to dial somewhere to get your mail.We will need to fix this, so the first thing to try is to configure Windows to never dial.

1. In Windows, open [Start — Settings — Control Panel]

2. Find and open [Internet Options].

3. On the Internet Properties, select the Connections tab.

4. Check the box for “Never dial a connection” and click [OK].

5. Go back into Outlook Express and click [Send and Receive]. If your inbound mail inUUPlus appears in your Inbox in Outlook Express, then everything is set.

• If the Dial-up Connection window continues to appear, then your UUPlus account in Outlookmay be configured to dial. What you should try is to specify how Outlook is going to connect.

1. On the Outlook menu bar, select [Tools — Accounts].

2. Select your UUPlus account (probably named localhost) and click [Properties].

3. Select the Connection tab.

4. Check the box for “Always connect to this account using” and select “Local AreaNetwork” from the pull-down box. Click [Ok] when finished. This should turn off theWindows dialer.

5. Go back into Outlook and click [Send and Receive]. If the dialer keeps popping up, trydisabling your other connections in [Tools — Accounts].

• When you click the SEND/RECEIVE button and you get the error message:

The connection to the server has failed. Account: ‘localhost’, Server: ‘localhost’, Protocol:POP3, Port: 110, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

The most likely reason is that port 110, which is used by the mailer and UUPlus Personal Proto communicate, is blocked by a email virus scanner. The solution is to change the port beingused by Personal Pro and your mailer.

In UUPlus:

1. Open UUPlus Personal Pro.

2. Select [Setup].

3. On the General Tab, find “Local Mail Server Ports.”

4. Change POP from 110 to 109.

5. Click [Done].

6. Shutdown Personal Pro and restart it.

In Outlook:

1. Open Outlook.


3. Select your UUPlus mail account, probably named localhost, and click [Properties].

4. Select the [Advanced] tab.

5. Change the Incoming mail (POP3) from 110 to 109.

6. Click [OK] and then [Close].

Page: 37


7. Click [Send and Receive] and see if it now works.

• If the “Connecting to Server” window displays but does not appear to be doing anything, theUUPlus window may be requesting you call now.

• If UUPlus is calling and you get one of the following errors:

“Your POP3 server has not responded in 30 seconds. Would you like to wait another 30seconds for this sever to respond?”

or:

“A time-out occurred while communicating with the server. Account: ‘localhost’, Server:‘localhost’, Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC19

Then you need to change the time-out length, or set UUPlus not to call on mail check.

To change the timeout in Outlook:

1. Open Outlook.


3. Select your UUPlus mail account, probably named localhost, and click [Properties].

4. Select the [Advanced] tab.

5. Change the “Server Timeouts” to its maximum setting (5 minutes).

6. Click [OK] and then [Close].

To change Call on Mail Check:

1. In UUPlus Personal Pro, select [Setup].

2. On the [General] tab, un-check “Call on Mail Check.”

3. Click [Done].

• If you continue to have difficulty configuring Outlook or Outlook Express, please contactUUPlus support.

Eudora.Eudora is a popular mailer developed by Qualcomm.

1. Install Eudora if it is not already installed.

2. Open Eudora. If you are opening Eudora for the first time, Eudora will begin the NewAccount Wizard. Follow the instructions for creating a new account. Click [Next] to begin.

3. Select “Create a brand new account” and click [Next].

4. Type in your name and click [Next].

5. Type in your UUPlus email address and click [Next].

6. Type in your UUPlus account name. Your account name is what precedes the “@”symbolin your email address. Eudora should correctly guess your account name. Click [Next] tocontinue.

7. Enter “localhost” as your incoming server, choose POP as the type of server, and click[Next].

8. Enter “localhost” as your outbound server. Eudora should already have this listed. Click[Next] to continue.

Page: 38


9. You are now finished with the account wizard, click [Finish] to complete the account.

10.The first time you check your mail, Eudora will prompt you for your password. If Eudoraproduces an error stating it cannot connect to “localhost” the most likely reason is the portused by the POP server is blocked. Eudora cannot change the port, you will have to use adifferent mailer or remove the third-party software blocking the port.

Section 8 The UUPlus Console Mailer.

The UUPlus mailer is a simple, limited feature mailer built into UUPlus software. It is easy to use andrequires little configuration. All mail in this mailer is viewed and composed in plain ASCII text. TheUUPlus Mailer does not support formatted text and does not display embedded images. It does,however, support sending and receiving file attachments, as well as including a spell checker.

• Main Window.

The UUPlus Mailer is composed of three panels: the Folders panel lists the folders for storingmail, the Contents panel lists the mail in the selected folder, and the Preview panel displays thecurrently selected message. New mail is always placed in the Inbox folder.

[UUPlus Mailer]

New Message: Starts a New Message.Address Book: Opens the Address Book. Each mailbox contains its own address book.Add To Book: Adds the selected email to the Address Book.Search: Searches for any message containing a keyword or phrase. Any messages containingthe keyword or phrase will be listed in the Contents Panel.Settings: Opens the Mailer Settings window.Re-Scan: Updates the listings in the Contents Panel. By re-indexing the mailbox, any new mailwill appear.Done: Exits the mailer.

• Folders Panel.

The Inbox, Receive, Sent, Draft, and Trash folders are reserved and cannot be removed. Anyfolders below the dotted line are defined by the user and can be added and deleted as needed.

To view the contents of a folder, double click on the folder.Add Folder: Right click in the Folders panel and select [Add Folder].Delete Folder: Right-click in the Folders panel and select [Delete Folder].

• Contents Panel.

Move To: Moves the selected email to a specified folder. This helps keep the user’s mailorganized. When the UUPlus Mailer opens, it re-indexes all the mail in the Inbox folder. As thenumber of messages in the Inbox increases, the longer it will take for the software to open. Toprevent this slow down, store mail in a folder other than the Inbox.Del: Moves the selected email to the Trash folder.Reply: Creates a reply to the sender of the selected email message.Reply All: Creates a reply to all address (except yours) in the To: line and Cc: line of theselected email message.Forward: Forwards the selected email message to a new recipient.

Return: Bounces the selected email message back to the sender.Raw: Displays the message in raw mode. The raw mode will show all formatting code.Print: Prints the selected email message.

• Preview Panel.By double clicking on a message in the Contents panel, the email message will appear in its ownwindow.Save Attachment: Saves the attachment to a folder. The attachment can then be opened.

• Mail Settings.

The mail settings contain all the individual settings for your mailbox. These settings apply to yourmailbox only. If you are opening a mailbox for the first time, the Mail Settings window willautomatically appear. Otherwise click [Settings] to open the Mail Settings.

[UUPlus Mailer Settings]

Reply-To Address: The address which will display on the “From” line in your mail. This addresswill be used to route mail back to your mailbox when somebody replies to mail you sent.[Edit] To the right of the Reply-To field is an edit button. The UUPlus mailer allows you to enterup to three alternate addresses for the From: field. Clicking the Edit button brings up a text editorwhere you can add up to three more address, the first address in is your default Reply Toaddress. Be sure to format the addresses you enter correctly.Edit Signature: Allows the user to edit the signature file. The signature file contains informationthat needs to be added to every outbound message.Automatically add Replies to Address Book: When checked, addresses you reply to will beautomatically added to the address book.Close Mailer When Inbox is Empty: Closes the UUPlus Mailer automatically when there is nolonger mail in the Inbox.Empty Trash on Exit: If you want deleted mail to actually delete on exit, check this option.Autosize Columns: The mailer will size the Subject, Sender, Date, and Size columns to fit themailer window size.Show grid lines in Mail Boxes: Displays grid lines in the pane listing mail.Always Refresh. Check this to always refresh the message list after a call, regardless of whatwindow has focus. If you are using “Chat” mode, check this option.Always use Raw Message View: Displays the selected email in raw mode. Any formatting codeor attachments will be displayed as ASCI characters.Scan for New Mail: While open, the mailer scan for new mail while the mailer is open.

• Composing Mail.

The UUPlus mailer features a basic message composer. This mailer is designed for satelliteemail so it sends messages in plain text, doesn't support in-line graphics or all of the rest of thegoodies that bandwidth hogging mailers support.

[UUPlus Mailer, Composing Mail]

• Send. Sends the message. You can also use the <ctrl><Enter> short-cut keys to send. Ifyou have not entered an address you will be prompted to do so.

• Address Book. Click to bring up the Address Book. See section 18.7

• Spell Check. Spell checks the message. You can also set your spell checking options.

• Save. Saves a copy in the Draft folder. Note that messages are not automatically saved.

• Print. Prints the message body.

• Cancel. Close the mail composer without sending or saving the message.

• Attachments. Brings up a file selector. You can also just drag and drop attachments on thecomposer. A window will appear showing the attached files. To delete an attached file, selectit, right-click and click Delete.

• Add To Book. Add the addresses in the To: and Cc: fields to the Address Book. Note thatyou can have this done automatically, see section 18.5.

• From: The composer supports up to 4 From: lines, use the drop-down box to select. Seesection 18.5 for more information.

• To:, Cc:, Bcc: Click the appropriate button for To:, Cc: and Bcc: (blind cc) addresses. Notethat you must have a To: address.

• Subject: The subject for the message.

• Address Book.

The UUPlus Console Mailer Address Book is very simple, it's features should be self evident.

[UUPlus Mailer, Address Book]

To add an address to the To:, Cc:, or Bcc: fields, select one or more addresses and click therespective button. If you are selecting only one address you can dbl-click on it and you will bereturned to the composer. Use the [New], [Edit], and [Del] buttons as needed.

Clicking the [Memo] button brings up a text editor for attaching notes to the selected address.

Section 9 Setting up a Local Area Network.

This section briefly covers setting up a small local area network (LAN) for email access to a computerrunning UUPlus Codan Server.

It is assumed that all computers have network cards installed and these are working, and that youalready have the necessary cabling and a hub, and the computers are connected to the hub. Using aWeb browser to access the Internet will not be discussed. It is also assumed that you know how tobring up a command window and how to access Windows Networking.

For use in private networks two ranges of IP addresses have been set aside: 10.0.n.n and192.168.n.n, where “n” is replaced with a value between 0 and 254 inclusively. For our examples,we will use a network using the range of 192.168.0.0 to 192.168.0.254 and all machines willhave a subnet mask of 255.255.255.0.

In our system we will not be using a DHCP server, so all computers will have static IP addresses. Wewill also set aside address 192.168.0.1 for future use by a fire wall.

In our example, our UUPlus Codan Server computer is assigned the address 192.168.0.2. This isdone by right-clicking on Network Neighborhood (on the Windows Desktop), selecting Properties,selecting the adapter we wish to configure (this is probably labeled “Local Area Connection”, right-clicking on the connection and clicking Properties, then selecting Internet Protocol (TCP/IP), clickingand clicking Properties. You should now have a window that shows “Obtain IP address automatically”and “Use the following IP address” (note that the exact wording varies from version to version ofWindows). Check “Use the following IP address”, enter “192.168.0.2” for the IP address,“255.255.255.0” for the subnet mask, and “192.168.0.1” for the default gateway. If you haveany DNS server address you can enter them, but they are not needed for accessing mail from theCodan Server server, so we won’t cover that here.

Repeat the above for all computers on the network, assigning each computer a unique address in the192.168.0.n range. Note that “192.168.0.” will be the same on each computer, you will need toincrement the value of “n” for each computer. All the rest of the settings will be the same on eachmachine.

At this point you should be able to open the command line window and type “ping 192.168.0.2”from each computer on the network and get a positive return. If you do not, check your hardwareconnections, make sure the networking drivers are installed correctly, and check your IP addressconfiguration.

Once all the computers are able to “ping” each other, all you have to do is run Codan Server, then inthe mailers on each machine type in the IP address for the Codan Server server (in our examplenetwork this will be “192.168.0.2”) in the POP and SMTP server fields and if your usernames andpasswords match the accounts on the Codan Server server, you are good to go!

Section 10 Connecting to the Internet.

This section presents five scenarios for connecting a UUPlus Codan Server to send and receiveInternet email. The first three detail the settings for connecting to a standard Internet Service Provider(ISP) using Windows Dial-up Networking or a full time connection and the POP/SMTP protocols. Theforth scenario details the settings for connecting to a corporate mail server across a local areanetwork (LAN). The last scenario details the settings for connecting to a UUPlus SOHO Pro servervia HF for the mail feed.

Numerous different mail setups are available from ISP's, the most common by far is POP3 forreceiving mail and using SMTP for sending mail. POP3 accounts come in basically 2 forms, a singleuser account (one mail box for each user), and a multi-user account (several user's mail is put in asingle mail box).

ISP's provide email address in one of two formats, either under their own domain, such as:<[email protected]>, or under a domain that you have registered, such as <[email protected]>.

“Fetching” mail refers to the process of connecting (either by dial-up or by full-time connect) to an ISPor corporate mail server to get the contents of one or more mail boxes using the POP protocol whileconcurrently sending outbound mail using the SMTP protocol. If more than one mail box is “POPed”,the term “multi-POP” is used to describe the process. If more than one user shares a single mail box,the process is called “multi-drop”.

When UUPlus fetches mail, it can access any combination of multi-POP and multi-drop accountsfrom any number of accessible mail servers, not just the ISP's server.

• Configuring UUPlus for ISP Multi-POP Accounts (no domain).

In the case where your organization has no registered domain and has several mail boxes at anISP, your email addresses will be in the format of <[email protected]>, <[email protected]>, etc.

In UUPlus Codan Server Setup, the Station Settings tab, the following settings are suggested,note that “myorg” could be any 16 or less character string using the characters a-z and the dash(-) and underscore (_) characters.

Smart Host: ISPUUPlus Name: myorgFull Internet Name: myorg.isp.net

On the ISP Settings tab you will need the following:

Use Dial-Up Networking checked with the entry selectedISP Login: user1ISP Password: letmeinSMTP Server: mail.isp.net

For the fetching entries, you would have something like:

user1 mail.isp.net user1 letmeinuser2 mail.isp.net user2 letmeoutuser3 mail.isp.net user3 letmego

UUPlus Codan Clients that connect to this server should be set as:

Full Email Address: [email protected]

Page: 44


Note, however that the email address set in the mail user agent (Outlook, Eudora, Pegasus, etc.)should be <[email protected]> (without the “myorg.”) so that mail is routed correctly. The “myorg” isused only as a identifier between the Client and Server during transmission.

The problem with the above setup is that mail from user1 to user2 will actually travel to the ISPand then back before it arrives in user2's mail box on the Codan Server. This can be overcomeby using either of the following formats for sending local mail:

<user2@myorg> or <[email protected]>

The other possibility to set the Server as:

UUPlus Name: ispFull Internet Name: isp.net

and the Clients as:


This setup is very clean, but you will not be able to send messages to any other users at isp.netas the Server will determine they are unknown local users and send the mail to the postmaster.For this reason you might consider getting a registered domain name. All other mail will flow asexpected.

• Configuring UUPlus for ISP Multi-POP Accounts (registered domain).

In the case where your organization has a registered domain and has a mail box for each user atan ISP, your email addresses will be in the format of <[email protected]>.

In UUPlus Codan Server Setup, the Station Settings tab, the following settings are needed:

Smart Host: ISPUUPlus Name: yourdomainFull Internet Name: yourdomain.ext


Use Dial-Up Networking checked with the entry selectedISP Login: accountnameISP Password: accountpasswordSMTP Server: mail.isp.net


user1 mail.isp.net user1 letmeinuser2 mail.isp.net user2 letmeoutuser3 mail.isp.net user3 letmego



The email address set in the mail user agent (Outlook, Eudora, Pegasus, etc.) should be<[email protected]>. “yourdomain” is used only as the identifier between the Client andServer during transmission.

There are no mail routing problems with this setup, however, you must contact your ISP to

Page: 45


add/remove users to your system, that is, for each user on your system the ISP must have a mailbox for (unless the user does not receive Internet email).

• Configuring UUPlus for an ISP Multi-Drop Account (registered domain).

In the case where your organization has a registered domain and your ISP puts all mail to thatdomain in a single mail box, you must use UUPlus' multi-Drop setting. Your email addresses willbe in the format of <[email protected]>.


Smart Host: ISPUUPlus Name: yourdomainFull Internet Name: yourdomain.ext


Use Dial-Up Networking checked with the entry selectedISP Login: yourdomainISP Password: accountpasswordSMTP Server: mail.isp.net


multi-drop mail.isp.net yourdomain accountpassword

You could also have other entries, such as:

user1 mail.isp.net user1 letmeinuser2 mail.someother.isp user2 letmelive



The email address set in the mail user agent (Outlook, Eudora, Pegasus, etc.) should be<[email protected]>. “yourdomain” is used both as as the identifier between the Clientand Server during transmission and in routing mail.

The problem with mail routing with a multi-drop account is when receiving mail from a list-serveor when an email address is a BCC. Messages are routed based on the To: and Cc: lines in themessage header, so if the message is addressed to “multiple recipients of...”, the message willgo to the postmaster mail box. It can then can be forwarded to the correct user (If you can guesswho it's actually to).

• Configuring UUPlus for a Corporate Mail Server Multi-POP.

In the case where your Codan Server connects to a corporate mail server it is assumed that thereis a mail box for each user. Email addresses will be in the format of <[email protected]>,or whatever form your corporate email addresses are in.

Note that these settings will work over a LAN, a full time Internet connection, or a dial-upconnection to a local ISP.

Page: 46



Smart Host: ISPUUPlus Name: hfusersFull Internet Name: hfusers.yourdomain.ext


Use Dial-Up Networking un-checkedSMTP Server: 192.168.0.2


user1 192.168.0.2 user1 letmeinuser2 192.168.0.2 user2 letmeoutuser3 192.168.0.2 user3 letmego



The email address set in the mail user agent (Outlook, Eudora, Pegasus, etc.) should be<[email protected]>. “hfusers” is used only as the identifier between the Client and Serverduring transmission.

In the above examples, a static IP address in dot notation is used for the POP and SMTPservers. On a corporate network mail servers usually are assigned static IP addresses so thesecan be used. This eliminates the need for UUPlus to perform a DNS lookup for a mail server onthe network and the need to configure a local DNS server.

There are no mail routing problems with this setup. Each user on the Codan Server must have amail box on the cooperate server (unless the user does not receive corporate email).

It is also possible to have the corporate mail server route mail directly to the Codan Server ratherthan using fetch. In this case, the corporate mail server and the Codan Server must be in thesame Class C, that is, the first three groups of numbers in the IP address of both servers mustmatch. If the corporate server is 192.168.0.2 and the Codan Server is 192.168.0.5, all is good.However, if the Codan Server is 192.168.1.2, it will refuse connections from the 192.168.0.*branch of the network.

• Codan Server as a Multi-user Client to a UUPlus SOHO Pro Server.

In addition to fetching mail from POP/SMTP servers, UUPlus Codan Server can receive it's mailfeed via Codan HF modem from a UUPlus SOHO Pro server. The Codan Server can function asa multi-user “client” as well as a “branch” node, servicing remote users who connect to it via HFas shown in the following diagram:

ISP <=LAN=> SOHO_Pro <=HF=> Codan_Server <=HF=> Codan_ClientEmail address format will vary from setup to setup depending on the parameters set on theSOHO Pro server, but the most likely email format for the Codan Server and Clients will be in theformat of <[email protected]>.

In the examples below, we will use the following names in our system, given that we have theregistered domain of “bishop.org”:

Page: 47


ISP <=LAN=> bishop <=HF=> knight <=HF=> pawnIn UUPlus Codan Server Setup, the Station Settings tab, the following settings are needed:

Smart Host: bishopUUPlus Name: knightFull Internet Name: knight.bishop.org

On the Mail Server tab you will need the following:

UUPlus Site Name: bishopPassword: letmebeSite's Station Address: 1001



The email address set in the mail user agent (Outlook, Eudora, Pegasus, etc.) should also be<[email protected]>. “knight” is used both as the identifier between the Client andServer during transmission and by “bishop” to route the mail to “knight”
