What you're looking for is a reverse proxy, or in this case, a TCP reverse proxy. I believe only NGINX plus (paid?) supports that. You're probably better off using haproxy.
I haven't done it so I can't help in that front, but I found this: https://www.linuxbabe.com/mail-server/smtp-imap-proxy-with-haproxy-debian-ubuntu-centos
Which is close to your scenario (I just looked at the first result). Otherwise the search term "haproxy imap" or "haproxy mail server" may help you find something, maybe throwing in wireguard or VPN.
Thank you! It never occurred to me to consider haproxy to do something like this and I think it is exactly what I am looking for. It's definitely worth further exploration. My subscription for email service is about to run out and I'd rather not pay for something I don't have to.
Just so you know, running an email service isn't as easy as you think. You'll most likely deal with a lot of blocks from Gmail and the rest.
I realize this could be a possibility. I don't think it is going to be easy but I'll give it a shot.
Good luck!
Here's a fun little talk about email hosting y'all had me thinking of.
You can do TCP proxying with nginx but many of the same features available in haproxy are behind the paywall. In nginx, layer 4 connections are dealt with through streams. You can do both TCP and UDP. I stick with haproxy for TCP streams with very few exceptions. HAproxy is most definitely more robust for situations where you have a pool of upstream servers. For single upstream instances, it’s not terrible. Most of the features I would use for better control of how the failover and balancing would work isn’t available in the open source nginx.
