I’m not on any of those blacklists, luckily. I guess Proofpoint doesn’t publish theirs. At least iCloud and Gmail both use them. I saw one hint that they may require mail servers to literally have the word “mail” as the subdomain, so I’m working up the courage to mess around with my perfectly working DNS.
