Why not use Gmail's own spam filter to eliminate the spam? It works pretty well and doesn't require you to use or maintain SpamAssassin. Use Mutt with IMAP and the messages will stay on the practically limitless storage space of Gmail's server. Use GnuPG for any messages critical of say, Janet Napolitano, and live a simple life.
