First of all thank everyone for your replies.

I haven't been clear on one point, my fault. We have to stay on Exchange, 
and users have to keep on using Outlook Web Access, this is a must in my 
situation. But we considered that users can connect directly when in the 
office, and from home or wherever they can use web access, so imap is not a 
requirement right now  ;-).
We would like to have a front web server that could redirect to the correct 
exchange web page depending on the login. In this scenario, even if I have 
no experience with reverse proxying, it looks to me like the best solution 
(any other tip or different opinion is very welcome). If I'm not 
misunderstanding it, it looks like we could have 1 only web server with a 
public IP, and the users would be redirected to the correct Outlook web 
access.

Thanks again, have a nice day
Simone

You would have a problem with SquirrelMail in that it only allows you to 
have one backend IMAP server for the entire site / implementation. The 
work around would be to have 3 different copies of SquirrelMail sitting 
around.
