Hi Chris,

I've used Cyrus, Courier and UW-IMAP. At the moment I think my
preference is for Courier  as, IMHO, it has a good balance of features
against ease of setup / use. I specifically wanted one that would
integrate best with my LDAP directory. Plus my mail server is a closed
box to users so I didn't wants their accounts in /etc/passwd, etc...

Regards,
Neil
