I've looked around in the docs and on the list archives for TLS support in qpsmtpd but haven't found any information. Is this functionality that still needs to be done? Or maybe it's something that can be accomplished using the Apache::Qpsmtpd plugin with mod_ssl?
I think the consensus (in July/August 2004) was to use stunnel as a wrapper around qpsmtpd, e.g.
exec tcpserver (flags) stunnel (flags) qpsmtpd
and stunnel (of recent enough vintage) will just proxy the SMTP transaction for you.
