I keep seeing people say "well if you have postscreen, greylisting is just dumb".
Well what is the equivalent for other MTA? I still see a lot of spambots on PBL hosts, that never contact again. So the blanket statement "bots are recoded" just doesn't jibe with what I see. Maybe you could many bots, or newer bots, but not all of them in current usage recognize the 4xx, wait and retry. ________________________________ From: @lbutlr <krem...@kreme.com> Sent: Sunday, July 31, 2016 8:55 PM To: users@spamassassin.apache.org Subject: Re: Is greylisting effective?

Yeah, that about sums it up. Greylisting never worked well, always caused problems with lost email, and in 2016 is simply a bad idea. Not just a not good idea, but a bad idea.
