Hello fellow self-hosters. Is it possible to use NGINX as a proxy for an IMAP service where the IMAP server is located on a different host? I have a cloud VPS running NGINX which is connected to my home network via a WireGuard tunnel. What I would like to do is run the IMAP server (Dovecot) in my own network and have NGINX proxy the connection. I have tried doing searches based on this but the examples don’t show how to specify the IMAP server for the connection to be redirected to for the lack of a better phrase. I know streaming is possible. Would this be the way to do?
I would love an example to go on. Thanks very much!
I actually considered doing port forwarding and NAT for this but I would run into a problem with NAT reflection. I’d have to implement split-brain DNS to avoid this. It’s more efficient to simple proxy the connection. If I am unsuccessful, however, I will resort to port forwarding.
