Help! I did some package updates and now I can't receive any external email

Update - It seems the config got hosed after the updates. Could be unrelated, but I restore the webmin config of postfix and the problem is now fixed. I am getting a bunch of emails from various servers telling me my server was spitting out a postfix config warning which of course did no good because I couldn’t get the mail.

Today I did these package updates. It seems ever since no external mail is making it into the server, even in maillog. Anyway I think I’m good now.

I removed and reinstalled postfix and some email came in, but I am not sure if that is coincidence or because of what I did. Unfortunately I have been unable to duplicate this which is why I am not sure if that is what caused it.

Is there a way to rollback to the previous state before these updates? Any other thoughts?

My main.cf and master.cf did not change during this.

I’m at a loss.

Howdy,

There unfortunately isn’t a way to revert to a previous state, except by using backups.

Just to verify though – are you saying the problem is corrected now? Or are you still seeing problems?

Yeah there was a config problem in Postfix. The restored config fixed it. I couldn’t find the cause of the issue though. Thanks for following up.
