FWIW, a couple of my regular correspondents have said that DO generally does not have a great email reputation, and that they're moving lists to other platforms.
That's probably correct, but are there other cloud VPS providers that are better at hosting MTAs?
FWIW, mail.python.org which hosts hundreds of MM 2.1 and MM 3 lists including this one is a DO droplet. I do note that DO is currently listed at UCEPROTECT-Level3, but IMO, that's a racket. I.e. they list your hosts entire ASN ranges, but if your single IP is clean, they'll whitelist it for a price ranging from 25 CHF (about 26.50 USD) for 1 month to 90 CHF (about 95.50 USD) for 2 years
I don't believe what AT&T is doing has anything to do with DO or any other cloud platform. The IP addresses of my Mailman servers (both 2 & 3) all have a IP reputation score of 97-99 with Senderscore.org and AT&T is still randomly blocks a server out of the blue. Linode is my cloud platform and they are also listed with UCEPROTECT-Level3 but no one uses that RBL to block email because what they are doing amounts to extortion.
