Problem with outlook and pop3

This is unexplainable: many outlook clients complain that every now
and then they're asked for username and password. The system
seems to work correctly after that, but outlook just keeps asking for
authentication...

I've looked in the logs and there are no slow queries, so I can't understand
why this happens.

Does anybody has an inkling of where I should look into?

Thanks.

Too many clients connected to the database server.
Ldap server (or AD) down or suffering from network problems.

Hi Giulio,

I've seen microsoft clients give the username/password prompt when it
was unable to connect.

Check the amount of allowed pop3 or imap processes. Search for
MAXCHILDREN in your dbmail.conf file.
If you are using MySQL, check the max_connections setting in your my.cnf
file too.

Once I've even written a perl script bogus pop3 'daemon' that allowed
every username / password to connect and say that there were no new
messages. That way if my pop3 server was down for maintanance, outlook
wouldn't reset the users passwords.

Grtz, Casper

It turns out that the problem was with misconfigured outlook clients due to
carelessness of the help desk...

Thanks anyway to all who answered.
