Proxy mail server

Is your feature request related to a problem? Please describe.

I am trying to proxy a mailserver but the task seams to be impossible at the moment with NPM whit this is possible to do with Nginx.

Describe the solution you’d like

I’d like the option to stream proxy mail serves as described here: https://docs.nginx.com/nginx/admin-guide/mail-proxy/mail-proxy/ I tried to stream the ports but the protocoles imap, smpt and pop3 are not supported by NPM.

Describe alternatives you’ve considered

The only alternative that I can think is manually configure the mailserver with the “Custom Nginx configuration” option but the reason why I am using NPM is because I don’t know how to deal with Nginx directly.

Is there and progress on this implementation or fearure request? Would love to see this natively in NPM. Having my mail services beging NPM with an ssl cert. (The described docker tip is too complex for me to understand).
