Hello Team, My goal was to disable Amavis and ClamAV for lowering my RAM consumption. 1. Commented lines in /etc/postfix/main.cf - restarted postfix . I have followed the instructions here (faqforge.com/linux/controlpanels/ispconfig3/how-to-disable-spamfilter-and-antivirus-functions-in-ispconfig-3) When I sent a test email I found this in the logs "Sender address triggers FILTER amavis:[127.0.0.1]:10026; " I have found no trace of port 10026 in any postfix configuration files (main.cf / master.cf) 2. I tried commenting a reference on Amavis in master.cf and restarting (commenting Amavis lines) The same thing in the log messages, sender address triggers Amavis. The curious thing Only after I reload the postfix configuration (postfix reload) and requeue emails (postsuper -r ALL) the emails are being sent - but only those that failed to be sent. If I send another email after reloading and requeing, I get the same problem of triggering the amavis filter. It only gets solved after manually requeing emails again. 3. Tried system reboot. Tried multiple service restarts (postfix, amavis). Same thing I don't understand Where is a reference of port 10026 in any postfix configuration? Why are emails being sent only after manual requeue ? I did installed the DKIM patch. Just 10-12 Days before I updated to ISPConfig Version: 3.2.8p2.
