Imapd in SuSE-8.2 does not work

Within mozilla-mail, I set up my email account so that it moves emails from /var/spool/mail to ~/mbox by using imapd. After the upgrade of SuSE-8.2, it suddenly does not work anymore. I enabled imapd from xinetd configuration. Therefore, it should work. I hate experimenting with pop3 becasuse it will erase all my email filter setup. That will be a disaster. Does anyone experience same trouble? Thanks. G. H. S.
