Re: Mail server dovecot restart failed.

why u use such old and outdated versions, both from centos and iredmail?
2008-06-24 was the 5.2 release, and is no longer maintained for a bunch of time

Re: Mail server dovecot restart failed.

Dovecot 1.2.16 is tooooooo old and i cannot help much. sad You have to try Google.
Try to upgrade to the latest 2.1.x (not 2.2 or 2.3) for testing.
