Wrote an Ansible role for this. Have a 10/10 score on mail-tester for outbound but I mostly use it for creating an alias everytime I register somewhere. If a site is sending me annoying emails i can prune their alias, and then it's like having a layer 7 firewall that tells them off with a bounce.
Still send family mail via Proton.
Tbh, that's what I want the mail server for right now. I was thinking that I could use it for aliases and signups now and maybe, if I see that it works and isn't too hard to maintain, I can eventually move over to mainly use it as my main email server. I don't know much about Ansible tbh, is that script open sourced anywhere?
If you are mostly looking for email aliases, then AnonAddy could be interesting for you as it can be also self hosted: https://addy.io/self-hosting/
