As of today we have been experiencing extremly slow connections to our

IMAP server.  So far we have been unable to detemine any cause.

DNS lookups are frequently the cause of this sort of problem. I would make
sure you can access DNS from the server, and that you can resolve the IP
addresses of the incoming clients.

Yeah, this was my thought when I read the original post.

The poster may like to check their patching levels. You may also wish to try truss(1)ing the master process with timestamping and tracing forks, only after it's slowed down (to reduce noise in the logfile), to see where things are slowing up.
