Hey-ho πŸ‘‹

What is the best approach for selfhosting an email server with static IP or blocked port 25?

I've done it many times in many different ways, now doing it again and want to hear what is the best approach these days

My port 25 isn't even probably blocked, I just prefer to use my vps to help it with this stuff

Any suggestions?

Hosting email with mailcow dockerized worked pretty good on my netcup vps, but before you go into hosting email ask yourself a few questions:

  • Will you use your selfhosted mail for important things? (Banking, official correspondence and so on)
  • Can you promise a near 100% uptime? Otherwise, some email might not reach you.
  • How important is the Mail you send? Some (stupid) Blocklists generally block all IP ranges that are sold out by vps companies and other kinds of IAAS.
  • If you register any accounts with your selfhosted mail, can you guarantee yourself that your email account is secure? Don't underestimate what an attacker can do with a compromised Mail account.

I personally ended up scrapping my email server eventually. Nowadays I pay a company to do the mail hosting, you just need to set some DNS records and they do everything else. Personally, I'm with proton, but there are many good alternatives.

Can you promise a near 100% uptime? Otherwise, some email might not reach you. Just lol. Mail get queued just fine by everyone. If you really concern , setup second MX.
