I did find this thread: > > http://www.nntp.perl.org/group/perl.qpsmtpd/2005/07/msg3404.html 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. Steve --
