Make sure you add yourself to dnswl.org if you're running a mailsever. Lots of people who use Spamassassian will check it (by default, it's part of the base install) and if you put yourself in there you will score yourself a few negative figures to help get your mail delivered.
Of course DMARC, DKIM and SPF are key as well.
I've run my own mailserver for the last 20 years and properly signing messages and being sure not to accept/forward spam (i use rspamd) has helped me be able to have a stable personal server all those years.
The only places I have trouble with are Microsoft, because it seems if you don't send a mail every 24 hours your reputation gets "reset" and it can be hard to deliver into them.
