@pteryx I set up my own email server on DigitalOcean and instantly got blacklisted by Spamhaus because it was a new domain, and then by another company because the IP address belonged to DigitalOcean. Most mail servers also flagged it as spam because the domain was less than 60 days old and because it was a .online TLD. For a long time, some of my emails were immediately bounced back or went to spam folders because of all these reasons. I also believe that every home IP address is automatically blacklisted, which makes it worse for your roommate. You can eventually overcome it by letting the domain reputation slowly develop and then doing a direct appeal to the blacklist companies. But, it takes a long time. It's amazing any spam gets delivered.

Some of that isn’t quite the case. I run an email server quite successfully on a residential IP, with no valid PTR. And I’ve added recent domains without getting them blocked. I’m not sure if the age of my primary domain (20ish?) might translate to google etc trusting any other domains from the same IP and DKIM key perhaps. But I’ve literally never had to dispute a block, ever. From all the horror stories I read, apparently I’m a unicorn.

@Jerry @pteryx Facebook bans my Selfhosted Server, frustrating. So I’m banned on all of Meta.

@Jerry @pteryx Some IP from DigitalOcean, or OVH make sometimes that the whole AS is considered suspicious. I remember when I had a dedicated server at OVH, I needed many time to gain reputation. Also, may be the previous user for the IP trashed the reputation. I also remember later, with a server at other place that I needed to ban the AS for several weeks to prevent flooding in log by trivial attacks. Create good reputation need time. And, sometimes you need fill form (for Microsoft) with IP.
