I am looking at MIAB to see if it can function behind an SMTP Proxy (SMTP proxy performs AV (Dual Scan), Blacklisting, Encryption, etc. The SMTP proxy handles both incoming and outgoing and I was unable to see if I would break MIAB if I edited the postfix server to use the SMTP Proxy as a smartest.
Looking forward to the comments because my current mail server is coming to its end of life (hardware wise)
