Electronic Mail
In the header area of the e-mail the sender identifies the intended recipient and the message’s destination by specifying the recipient’s Internet address
The e-mail message is first routed to a mail server
A mail server is a system that uses the e-mail address to determine where the message is going

The mail server also determines the most direct route for delivering the message
The mail server uses SMTP to send the message to the next available mail server or router
SMTP is part of the TCP/IP protocol

Each mail server contains a routing table, known as Mail Exchange (MX), that determines where to send the message next
