[Dovecot] mailserver pop3-login: Disconnected

Tue Dec 13 08:58:11 EET 2005

Good Day

I am having the following serious problem. I am
running CentOS 4.1 with dovecot 0.99.11. The users are
using POP3 login to retrieve mail. For the last 2 days
we have experienced the following problems. I have
recreated all the users and reconfigured the
dovecot,but the same problems occur.

Please see attached /var/log/maillog messages
It appears so users login whereas others
cant.Eventually after about an hour none of the users
can login.

If I tried to restart the dovecot i get the following
error

Fatal: Listen (110) failed: Address already in use

Is this because it is trying to restart when all the
processes havent been killed?

Your help would be much appreciated

Kind regards
