Hi, Yesterday I updated my Plesk 8.1.1 server (debian 3) server with apt-get. psa-hotfix was installed: 2007-12-30 13:39:21 upgrade psa-hotfix3 8.1.1-debian3.1.build81070423.14 8.1.1-debian3.1.build81070423.19 I believe after that all email accounts were still working, but this mornining I was no longer able to get or send any mail. After that I upgraded to plesk 8.3.0 in the hope it would resolve it. But now I still cant login to any mail account. For some reason newly created accounts do work. I cannot find anything strange in mail.warn/mail.err except a lot of Dec 31 04:37:25 psa imapd: 1199072246.966327 DISCONNECTED, user=info, ip=[22.214.171.124], headers=2584, body=40698, rcvd=9608, sent=104708, maildir=/var/qmail/mailnames/xxxxx.nl/info/Maildir Any help is appreciated.
