While I was working on this I found out I had a broken courier-webadmin package. So I figured updating that package would not cause any damage. And was I wrong. No all the sudden no one can connect to my mail server. The server can recieve mail. But no one can login.

So I figured my MTA is working, but my imap/pop3 server are screwed up. IE Courier is damaged. Now I use vexim to add users and vexim comes with some changes to /etc/courier/imapd - pop3d. All been detailed at the homepage.

Now im pretty sure I done the right modifications to imapd and pop3d. But I still cannot login and get mail. What could be wrong? /var/log/mail.log

vexim uses mysql to authenticate users. pop3d is altered to do this. What can be wrong? I tried the vexim maillists but no response. :/
