Properly configuring a mailserver
These docs explains (in depth) how to configure simple-nixos-mailserver and achieve a 10/10 mail-tester score.
Due to a lot of internet politics self-hosting a mail server isn't always super easy. TLDR a lot of VPS subnets get abused and get registered on blacklists. You should test your IPv4 address (or domain) on MxToolbox first. If you're not blacklisted you you'll only need to worry about writing out DNS records (very specific ones that avoid your emails going straight to spam).
