Well, I do use reject_unknown_sender_domain (however recently I temporarily turned that off due to some issue with legit emails, and I basically don't experience spam from domains that don't exist), but was actually not aware that it rejects null MX too... thought it only rejects domains that have no A or MX records at all...
