In my implementation the greylist check comes after the sender check. I'm doing the sender check in filter_sender and the greylist in filter_begin. So the sender check would save some processing for every mail it rejects even for mails that would have been stopped by the greylist (1: it would do a REJECT instead of the greylists TEMPFAIL and 2: it would reject before reciving the actual mail while my greylist rejects after receiving it (because of stupid mailers)).
