Luke, you're sounding like you've forgotten we know each other IRL, and the same goes for you and my biz partners Pekka and Catherine. We timeout new domains for a year or more, in accordance with https://www.m3aawg.org/documents/en/m3aawg-best-current-practices-for-building-and-operating-a-spamtrap-ver-120 We started out doing this in such a way that the domains didn't have a way of receiving any email at all (no A and no MX, resulting in the sending mail server having to tell itself NXDOMAIN), but already for a long time this is done so that they do have a mail server that is responding 550 5.1.1 No such user to every attempt to deliver any email. I agree that that should result in very little to no ESP mail when such a domain eventually comes out of timeout, which would result in our not having a business at all.
