I think the last time when you could do that was 25 or 30 years ago. Nowadays, you’re just going to enter a world of endless pain, suffering and frustration.
You can do it as an experiment if you want to experience how bad it is. Do it on something isolated that you won’t mind setting fire to afterwards.

So actually it’s not as bad as that. I feel like I should write a guide.
Absolutely the hardest part was getting a static IP. More on that in a second.
Exim and dovecot are very, very mature pieces of software. Exim is difficult to configure, but once you get there, it doesn’t ever change. Now that the AI tools have gotten good, you can learn and configure it quite quickly.
For spam- life is so much better with pfsense running pfblocker. Also,bi set up a fail2ban feed to pfblocker to block IPs spamming,brute forcing, or otherwise misbehaving. Much of this already existed in fail2ban and I just have it dump its blocklist to text via a cron job that pfblocker loads.
The good IP is the hard part. For a while I just paid for one, it was about $20 more here for business class Internet that came with an IP. Eventually I cut costs.
You can do this basically two ways. Just get a VPS and install the mail server there, or get a VPS and install opnsense or pfsense there, with a VPN tunnel back home to your mail server. Haproxy handles it and wireguard is really reliable. I did hit a snag here because Google are buttheads and blocked the IP I had - literally no one else does. I actually don’t have too many people who use gmail that I contact so it has only been a tiny problem. But the first IP I had worked perfectly for years.
You need to set up SPF, dkim,certificates etc. But these are just text strings and let’sencrypt…once all set up it just stays that way. Apply updates when released and enjoy your own email server, which is awesome.
