Here is an example outline of what happens:

1) Sending SMTP server connects to SMG (SMTP Interface)

SMG now has the sending server’s IP address. Soit can perform IP reputation check and RBL (if it is configured todo so)

This also means information that can be added toMessage Tracker (if it is configured to do so)

2) Sending SMTP server sends MAIL FROM command

SMG now has the sender’s email address. So itcan perform SPF check (if it is configured to do so)


We have more information that can be added toMessage Tracker

3) Sending SMTP server sends RCPT TO command(s)


SMG now connects or attempts to connect to thereceiving server and SMG begins the SMTP conversation with thereceiving server on the sendering servers behalf.

We have more information that can be added toMessage Tracker, including if SMG cannot connect to the receivingserver.

4) Sending SMTP server sends the DATA command


SMG now has the message (mime) and it can besent to the message scanner for full scanning


We have more information that can be added toMessage Tracker, including if the message was accepted by thereceiving server.

Throughout this process if the SMTP conversation is terminatedbetween the sending server and SMG or between SMG and the receivingserver (which also means if a firewall in the middle blocks theconversation), If message tracking is configure then I would expectto see some clues in the message tracking information.

It’s likely that a block due to a firewall will appear as a timeoutor lost connection.
