You asked for server-side options.  Procmail and SA are best
installed on the server if you want to cut down the download times.

With any reasonable ISP that provides you a shell account, you can
set up your personal rules in ~/.spamassassin/user_prefs

I use pair.com but there are many others.

You can actually do all that and more with spam.el, a package for Gnus
which I maintain.  Check out the CVS version of Gnus and look in the
manual (Oort Gnus comes with spam.el also, but many bugs have been
fixed meanwhile).  spam.el is sort of a framework, and inside it are
various flexible spam checks you can enable depending on your needs.
I would still do server-side filtering in addition to client-side
filtering, but that's your choice and moving away from swbell is
certainly going to be a hassle for you.

To only get mail headers, use IMAP.  There's more to it, I suggest you
read the Gnus manual in the spam.el section, but what you describe is
definitely possible - and you should continue the discussion on the
gnu.emacs.gnus newsgroup if you have any questions.
