Yesterday I updated all 5 of my servers with 3.1.15p3. This morning, I had no email for today. Normally I get email starting at 2am. So I checked the server and ran mailq and there are tons of messages stating: (delivery temporarily suspended: connect to 127.0.0.1 [127.0.0.1]:10024 : Connection Refused) I saw an old threat from 2015 and I ran the grep command for /etc/postfix/main.cf and the content_filter line is there for amavis and port 10024, and it's not commented. I have tried restarting amavis, restarting postfix, telling postfix to process the queue with "postqueue -f" but yet the email remains there. What can be done to get email flowing again??? At this point, all email here is down.
