Currently my Home UTM (9.204-20) has E_Mail protection enabled for all e-mail destined inbound to my mail server. At this time there is a firewall rule that allows the mail server to send out to the Internet and is using the correct public IP for outgoing mail when leaving the UTM.
When I go to enable DLP and set the UTM to intercept email or set the UTM as a smarthost for my mail server I am unable to send email outbound. I get the error message "Mail loops back to me".
The mail server system is postfix based inning on a UNIX os.
I have a feeling this is something simple but am not seeing it. Any ideas?
