Part of this is also the process of moving everything off my old laptop onto a 
new one... But I don't want to store everything on my new laptop until Ive 
configured the new the way I want. Im looking at possibly trying Sylpheed, 
but I generally haven't liked other clients (I want a mail client, plain and 
simple, not a contact/IM/etc manager).

Yes apples to oranges, but the first step is to actually get the mail copied 
to another store. Then I can compare different clients/access methods against 
the same store.
