I have had a pobox.com email address (just a forwarding one) longer than I've had a Gmail one, and their spam filtering was pretty amazing too. Even before I set my pobox.com address to forward to Gmail, I never saw very much spam.

Now that Pobox is owned by Fastmail, I rather suspect that Fastmail is going to have the same good spam filtering. Can't speak from experience, though, as I haven't actually used my new Fastmail account yet (it still forwards to Gmail, and so far I haven't switched. Momentum, again).
