I have greet_pause long ago enabled in sendmail.
Out of 1,112,871 messages yesterday only 1096 tripped greet_pause. If it occasionally trips up a miscoded client I tell them to fix it or stop using and am happy that this tiny effort made the internet a slightly saner place. But it's not in the same league at all. Between milter-greylist, and several measures, it covers quite a bit at the first layer, before we have to get to the expensive SpamAssassin stuff. The hate on greylisting seems a bit off to me. I realize it's not the most effective tool in my toolbox, but it helps. There have been this year malware blast campaigns, where I traced that the IP involved were blocked by the MX servers with greylisting, and examples that got through came through department MTA that did not. On the whole I'd rather have postscreen, but I don't make those choices. Thus we patch together a simulacrum. ________________________________ From: Axb <axb.li...@gmail.com> Sent: Monday, August 1, 2016 12:53:27 PM To: users@spamassassin.apache.org Subject: Re: Is greylisting effective?

There may be something similar for EXIM , QMAIL may have some obscure patch.. Axb
