+1 for Thunderbird. We use it here at the school where I work, and while I 
don't have people's exact file sizes and counts on hand, I can say definitely 
it handles a lot of email; most people have boxes dating back to 2004 and it 
hasn't been an issue.

I use Kmail for my own work machine just to keep up with the project but I am 
not prepared to have 'real' users use it yet. Still too many issues that I 
see, generally, on a daily basis.
