When dovecot works - it works great, and I thank you. But it seems like every time I setup a new server, it's a challenge getting the IMAP logins to work reliably.

The changelog's top comment is stamped 2007-01-05, 18:48 if that helps nail down the version (I'm using a Debian/Ubuntu package).

Both non-SSL and SSL logins have the problem. This time around I'm using LDAP authentication - and once I figured out how it worked beautifully. The problem is from time to time - with no particular consistency - I lose the ability to log in. A "telnet localhost 143" on the server works with a Dovecot response, then followed with a "01 LOGIN <user> <password>" results in a long delay, then a timeout, with no log files affected.

What can I provide to try to trace this?
