Related to your Exchange issues...

Last year, I talked the IT director of a very large Exchange shop where 
the IT department got "right sized".  As a result, they had to look for 
cheaper ways to deliver Exchange-like functionality.  They ended up 
moving to CommuniGate Pro using IMAP/webmail (executives,sales), POP 
(office dwellers).

CGP comes with a skin based webmail interface that you may like.  Also, 
there is no IMAP overhead for CGP's built in webmail.  It's directly 
accessing the mail spool.  As a result, it can perform very well.

If you want to make use of an already installed Outlook XX base (or ease 
migration from Exchange) you can look into their MAPI product.

We've tried it, and while not all the Outlook/Exchange features are 
there, a significant number are.  At least the ones I tend to use.  More 
importantly, they also have a full disclosure of what does and does not 
work.
