Why is Fail-2-Ban loading my Postfix queue with messages?
When I look at my maillog for evidence of mail sent by me from the server, the files are crammed full of messages from Fail-2-Ban.
I'm running a Postfix server on Centos 6. Currently I'm using it as send only. If a problem occurs with a recipient, I can barely find the recorded messages sent between my server and the target's server since my maillog is so cluttered with Fail-2-Ban messages. I don't remember specifically involving Fail-2-Ban during the Postfix set up. How does Fail-2-Ban get involved ?
