Seeing a lot of parallels to my own experience here with self-hosted email.
I had a personal server setup for $5 a month, handling all the mail for my immediate family. Did all the same hoops mentioned in the post, and still saw emails going to spam or “hellbanned”.
Ended up moving it over to Fastmail, it was far too much hassle to keep running and fighting blocklists.
@aral @cancel if that happens to fedi stuff, damn it’s going to be awful. Can’t let that happen again
