That thread, I think, is about presenting TLS to the clients
who submit mail - rather than piping from the proxy itself to
the upstream/"real" server.
When I've used qpsmtpd in the past I used the `exim-bsmtp` process
to talk to exim4 on the local-system. That didn't involve using
TLS, just a pipe.
The "smtp-forward" plugin doesn't seem to support TLS either, for
what that's worth.
Generally I'd assume:
internet -> qpsmtpd -> [exim|postfix|whatever on the local host]
So the lack of TLS on the final hop hasn't been a concern to me
personally. I can appreciate others might disagree.
