Postfix Stopped Working
After having postfix installed and working for about a year, it suddenly stopped working. I don't see any evidence of being hacked, and everything else seems to be working properly. I haven't run any updates, and am not aware of any auto-updating in place. I'm running Apache on Linux.
Has anyone else encountered a similar issue? I've been trying to get email back up all day, and have missed almost a whole day's work because of it. :P
