Getting this back on topic, would you be willing to share how you are sending outbound mail through AWS servers without it being marked as spam by nearly every blacklist out there? I know AWS let you set reverse DNS on elastic Ips, however whenever I send outbound mail via MX lookups directly on AWS servers it always gets blacklisted. My solution has been to use an expensive outbound relay.
Any suggestions on how you are doing this for users who purchase your Mailman marketplace image?
I suspect you are talking about ESPs marking incoming mails as spam rather than anti-spam blacklists here.
I've posted an article on the topic a while ago: https://blog.smirnov.la/how-to-send-emails-in-2020-3ad76a31a7cc
Also, there is a "warm-up" of a new IP for some ESPs (but not for all of them) - 1-2 weeks - that you just need to wait out.
Best, Danil
Thanks. Andrew.
