I would love to do this - and it would be easy, as I'm already forwarding from my own domain and have been for 25 years - but I receive so much spam (>600 per day vs. ~20 non-spam per day) that only Gmail's spam filtering is good enough. I've tried others (like Fastmail) and typically ~50/day get through their spam filters, vs. at Gmail where on a typical day 1-2 get through. As soon as anyone besides Gmail can successfully do spam filtering, I'm stuck with them. (Why do I get so much spam? Because I've been using the same email address, never hiding it at all even on Usenet, for 25 years.)
