Followed the how to for this http://www.howtoforge.com/virtual-u...x-courier-mysql-and-squirrelmail-ubuntu-12.10 a week ago, ran updates, and saw a new postfix install as part of the updates. When postfix restarted, it gave errors about config options that weren't supported in postconf. So I'm guessing the patch that was installed as part of the howto was overwritten by the postfix from the ubuntu repositories. What is weird is that email is still working for the few accounts I created - I haven't added any accounts since the update though. So... is this normal? Should I pin the custom postfix package? Or can I ignore the errors since things are still working? Or is the error only related to quota limits and the mysql for virtual users portion unaffected?
