Lean and clean IMAP client

[Rohan Nicholls <rohan.nicholls@informaat.nl>]

I have been using the mozilla imap client for my mail for a while now, 
and am finding it very resource hungry.

I have tried to get gnus working with teh exchange server at work, but 
it will only see the inbox, and not its subfolders, and I find the lack 
of multithreading (so stops while waiting for mail) a bit of a problem.

I am thinking of installing evolution on the advice of another user, and 
saw that it wants to install 30 megs of libraries etc. so that has made 
me pause, although the possibility of being able to access the ldap 
server would be nice....


I have read and searched the web and tried out various clients, but 
there are surprisingly few that imap happily.:)


I am looking for advice on: a lean imap client (I have switched to 
pheonix browser-wise and don't want the overhead of mozilla just for 
mail), and/or an ldap client that talks to exchange server.  If both 
come in the same package so much the better.  I use emacs a lot, so if 
they can integrate with emacs to allow me to compose in emacs I would be 
in heaven.:)

thanks in advance for any advice.
