Mail Protocols Proxy at System Level

i'd like to set up an app proxy server at local to resolve contents in mail protocols with SSL/TLS.

using VPN(App Proxy Provider only support HTTP?) to tunnel flows about mail protocols to proxy server seems impracticable

system configuration only supports HTTP and FTP?

is there a way to set a Mail Protocols Proxy at system Level? or is there a way to route all transport layer flows(not only particular Application layer protocol) to proxy server?

You’re targeting macOS, right?

If so, I recommend that you use a Network Extension transparent proxy. That allows you to intercept the connections you want and leave the system to deal with the connections you don’t.

is there a way to route all transport layer flows … to proxy server?

Once the transparent claims the flow, it can do whatever it wants with it.
