If they did, they would age them for at least a year before turning them into traps, by which time the DMARC records would be long gone. That's not it. I suppose someone could set up a malicious MX to aim random junk at mail servers, but Spamhaus' trap servers are pretty hard to find. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
