8 months agoFor a mail server, I use https://nixos-mailserver.readthedocs.io/en/latest/index.html . Very easy to set up, and it seems to work. But I do get a lot of anxiety about it because of all the people who say you should never under any circumstances set up your own mail server because of reputation and whatever. Just be aware that although mail-tester.com doesn’t ding you for it, you really have to make sure your rDNS entry is set up correctly, and you need your own /64 IPv6 range.
I’m not sure if this would cause the issues you are seeing, but ensure your hosting provider allows you to make outgoing connections over port 25. A number of them block it for spam reasons.
