UW Imap FC! to Cryus-imapd FCD broken E-mail

[test]

When I upgraded from FC1 to FC2 it installed cyrus-imap..which broke my 
pop3/imap clients.
I spent a day off and on trying to get it working. How do I get my pop3 
working again?

FC2 sendmail squirrellmail . No LDAP ..saslauthd and cyrus-imapd are 
started and running.

Sendmail is receiving ok..I just can't get authorized from clients ( 
thunderbird , OE .Outloook)
I  tried using pam ..NG...
It's currently using shadow by default.

I read the docs but can't get things working...,

Is there something I'm overlooking?
