exim+fetchmail, the best combo for local retrieval?

[Try KDE <trykde@rogers.com>]

To work with my ISP 's email cap limit, it seems to be a good idea to 
use a local server to fetch the emails first, and then use a client 
machine to finally retrieve them later (client machine is not always 
on).  Shyamal points out (on Oct 12) that he uses exim+fetchmail to do 
that. In your experience/opinion, is that the best solution, or any 
other recommendations?

Thanks,
