function send_email($servername, $emailaddress, $username, $password, $last_name, $first_name, $to, $cc, $su, $ms){ if (!empty($cc))$to=$to.",".$cc;$to_array=explode(",",$to);

$smtp = fsockopen($servername, 25);fputs($smtp, "HELO $servername \r\n");fputs($smtp, "AUTH LOGIN\r\n");fputs($smtp, base64_encode($username)."\r\n");fputs($smtp, base64_encode($password)."\r\n");fputs($smtp, "MAIL FROM: $emailaddress \r\n");for ($i=0;$i<count($to_array);++$i){ fputs($smtp, "RCPT TO: <$to_array[$i]> \r\n");} fputs($smtp, "DATA \r\n");fputs($smtp, "to: $to \r\n");fputs($smtp, "Subject: $su \r\n");fputs($smtp, "cc: $cc \r\n");fputs($smtp, "From: $first_name $last_name <$emailaddress> \r\n\r\n");fputs($smtp, "$ms \r\n\r\n"); fputs($smtp, ".\r\n");fputs($smtp, "QUIT\r\n");fclose($smtp);
