We have 2 pop/imap servers running with director.
Dovecot version = 2.1.12 Dovecot version = 2.1.13
Very first thing on your troubleshooting ToDo list should always be to make sure you are using the latest version of whichever series you decide to run.
So, you should upgrade to 2.1.17
Output of doveconf -n
# 2.1.12: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 CentOS release 6.3 (Final)
If you aren't willing to do that for political reasons (ie, phbfh) to do with the distro you are using, then your first line of support should be that distro's support service, because they may or may not have incorporated certain bug fixes in the older version...
