Sorry Charles, it was posted twice unintentionally (becuase of network issue).

We have 2 pop/imap servers running with director.

Dovecot version = 2.1.13

Please don't spam the list with multiple postings of the same question.

Most people do not have crystal balls, and those that do often find them 
broken, so it would be helpful if you could provide at least a bare 
minimum of details about your setup...

What version of dovecot is this? doveconf -n output? Singe server or 
cluster?
