In one of the threads it is said that opening port 6000 in the firewall would solve the problem with mails not going through when Scan Outgoing Mail is enabled. When the function is disabled everything goes through fine, but none of the functions in the Content Filter section works.
I have then tried to see where the problems lies within, by disabling Expression filters, AntiVirus, Extension and MiME error checking, and the mail still won't go through when scan outgoing is enabled.
Does anyone have an explanation of what is going on in the scan outgoing mail function?
At this point the server is set up to only deliver mail out of the house in a test-case, therefor it is placed behind a firewall, instead of in front. Another solution we have, is the vice versa, and it works fine when both recieving and sending mails.
The system runs on the lates ISO on Astaro.com (ASG 6.200).
