Gray listing is pretty much pointless in this day and age. Everything has moved to content, header and IP connection rep filtering, and consequently, mail has moved to large providers that can afford to invest more and hire more people to do this.

Folks, Time for a major change to spam handling for me. Possibly overdue. What's the consensus? In times where 2 factor authentication emails are frequently completely pointless trying to go through greylisting where they are delayed beyond their timeouts. But where spammers obviously still persist. Is it still worth trying to greylist, or rely on other methods instead? Is it the case where SMTP-time spam/virus scanning is a necessity and greylisting should be removed? How do other folks on the list balance out this conflict in their systems?
