I am looking into whether or not this is DNS related internally.

Hello,
I am experiencing IMAP authentication delays when a client first
authenticates, or after the last auth timeout. There are only a
handful of clients - less than 5 - using the server. I am using a
mysql database and I have verified the PAM auth is commented out.
Other than that I can't figure out what might be causing the slow
authentication. The first time a client authenticates with SSL/
CRAMD5 it takes almost 20 seconds. Does anyone have any
suggestions? My config and version is below:
