I didn’t have a “clean” ip so most emails I sent went to spam. But was rectified after recipients marked as safe or “not spam” on their end.

Not really an issue for me since I am not using it for mass marketing; and it’s just a personal email server. So just a single user (me).

There were issues with block lists and outlook but was fixed after IP reset. Fortunately most of these services provide near instant feedback via mail protocol or bounced emails.

Plus I have a metrics exported via Prometheus and feeding into influx db and grafana dashboard.

Also fun to monitor Dovecot and postfix logs and get them into grafana. The number of script kiddies just sending random requests is fun to watch. Had a couple of instances where attacker was clearly trying to find a vulnerable user and try to use my server for spam or something else.

I had a personal email server on linode for a while but a lot of my family uses gmail. Gmail wouldnt accept my emails and I ended up switching my domain to a commercial provider because it was such a pain in the ass. Never did mass emails or marketing, just my own personal use

Besides getting sent to spam, I haven’t had deliverability issues to gmail. All I needed to do was setup my DKIM, SPF, DMARC records correctly. Confirmed with mail-tester.com

I think linode may have had problems in the past with their assigned ip ranges being used as spam. Quickly looking into it, seems like they block outgoing email traffic by default now. But individual server owners need to manage IP rep.

I did all the same things and even registered my domain with google and added their verification DNS txt record. You're probably right about it being linode's IP range, although I did get permission from linode to use it as a mail server, they opened the right ports and I did get deliverability to other mail hosts just not google or my university at the time, annoyingly enough
