Hi all,

As mentioned in my previous posting, I'm now officially giving up hope
of any getting this botched upgrade from 2010.2 to 2011 to work.  Too
many errors, too many problems, too many headaches.

What is currently installed on my system for IMAP/POP3 service is the
imap-2006k package, which was available as part of the 2008 distro.  For
whatever reason, that's the one that's just stayed on my system through
a couple of upgrades.  It's not available now on the current 2011
version, so I might as well replace it with one of the
currently-maintained IMAP/POP3 packages.

I'm looking over my local copies of the mirror that I was using for the
upgrade (to speed the process by not needing to download that much
stuff), and I see there are two IMAP packages being provided:

courier-imap
cyrus-imapd

Which one should I pick?  If any of you remember the 2008 ML imap-2006k
package, which one of the above does it most behave like?  Or does it
even matter - IMAP is IMAP? :-)

If it helps, while users do store their own mail folders in their
$HOME/Mail directory, there is still /var/spool/mail where user inboxes
are located.  So if only one of the above supports both $HOME/Mail &
/var/spool/mail, that would be the one I'd want to be using.

So, any thoughts/info/opinions? :-)

               --Dave
