Its still not clear to me the difference between greylisting and greytrapping.From what I could gather with greytrapping you would also verify the RCPT address and promote the connect IP/sender to suitable black lists if no-such-RCPT-here. (I like this variant.)
Is it correct to say that greytrapping is basically enforced greylisting, disallowing the success of any retry for a defined interval? In your case, a 24 hour long blocking of the IP after initial connect? Are you still generally happy with it, feeling that it stops some significant amount of spam successfully? Beyond the limitation of this
For myself I've been happy with greylisting for years, though a more practical grey list time I use is 15 minutes, because when it is a real RCPT long delays can be annoying.
being doable on IPv4 only currently.
milter-gris and BarricdeMX shouldn't care about difference between IPv4 or IPv6 for greylisting.
