I am not sure if it is in MFE but it was configured to be a relay server for emails. Incoming/Outgoing mails were relayed to the firewall by my clients Antispam appliance. They are experiencing lots of bounce back emails after upgrading from version 7.0.1.02 to 8.2 and changing their external ip address when they switch to their new ISP. Below are the error messages.
Outgoing email: The errors below happened when one of their user is sending email outside their network.

I believe that mta.1 is the external burb while the mta.2 is internal burb right?
