I ran some updates last week and mail is no longer coming in or going out. From the bounce message (below) which was received by an external sender attempting to mail someone on the Virtualmin box, it looks like mail is trying to listen on port 10024, which is an Amavisd port, according to google. Apparently this got installed during a virtualmin update. Any suggestions on how to troubleshoot? Postfix is running, I can telnet to the server on port 25 and I have port 10024 open on the firewall, and I have disabled both Spamassassin and ClamAV (for now).
