I am not sure either. :-) I you want to help out, you could test postscreen's use of the server-side proxy with deep-protocol tests over TLS. I don't know how the proxy behaves when the server initialization does not run for lack of certificates. You'd still need to convince postscreen that it should offer TLS... I don't recall whether use of tlsproxy(8) with smtpd(8) is supported, there's presently no good reason to do that. -- Viktor.
