External email server vs port forwarding/vpn
Hey-ho 👋
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?

I do not understand why everyone calling hosting email difficult? IT is like 5 RFC you need to read and implement. Sofware wise you will need mail agent, something for DKIM ( if it not build in in agent), "local delivery agent" ( probably presenting it as IMAP) + mail reader of your choice. Nothing too complex
The complex part isn't the hosting part. Its the security part, the reputation management part, the uptime part, the troubleshooting delivery part and basically every other aspect other than running postfix+dovecot
It's not complicated until your reputation drops for a multitude of reasons, many not even directly your fault.
Neighboring bad acting IPs, too many automated emails sent out while you were testing, compromised account, or pretty much any number of things means everyone on your domain is hosed. And email is critical.
