[imp] Suggestions for wu-imap altenatives

[Mike DiChiappari]

I briefly looked into Courier-imap.  It looks like it could be "significant"
work for me.  I don't want this to be a major project.  I just want to
upgrade a small email server so people can get their via a web front end
(Horde/IMP).

The main problem seems to be that Courier-imap expects mail to be in a
different format (note I'm a novice here).  It expect "maildirs" while
uw-imap stores email in a different format.

Any suggestions for an IMAP implementation that can easily be swapped in for
uw-imap?  Keeping with the notion of making this a relatively painless
effort (if possible) an RPM for Redhat would be most convenient.
