I am installing a Symantec Gateway Security 5620 appliance. It has nice wizards for applying Anti-spam and Anti-virus for POP3 and SMTP. But, we are using IMAP for incoming mail and SMTP for outgoing mail. Our mail server is at another location, which we simply connect to via Internet.
From viewing the logs, outgoing SMTP traffic is being properly scanned with Anti-spam and Anti-virus settings. I cannot get the IMAP traffic to be scanned though. I had to create an IMAP protocol, but when I set my rule to use my IMAP protocol, Anti-Spam and Anti-Virus tabs are unavailable. So, I created a rule with a Source of my network and a Destination of the remote mail server, with a protocol of ALL. I can then set Anti-spam and Anti-virus...but the traffic never shows up in the log. The "log if successful" box is checked. The rule should be getting hit.
Bottom line, I need to have my incoming IMAP mail scanned with Anti-spam and Anti-virus. Thank you in advance for your help.
