The only problem with the twisted IMAP library is also missing
functionality. It lacks the acl handling as well as the annotation
handling.

Other than that it's pretty nice. It uses zope.interfaces which is a
big plus in terms of being object oriented. It provides nice client
and message objects. And this might make it far easier to code a
caching wrapper around the IMAP part.

I believe the missing functionality should not be too much of a
problem since the Twisted classes in general are not too hard to
extend. 

If people would choose this lib as the imap handler I would definitely
offer to get involved there since I already did some twisted
programming and like the concepts behind it.

Cheers,

Gunnar
