You'll need to join the postfix-users list via majord...@postfix.org, as explained at http://www.postfix.org/lists.html. I and others can only reply to your email if it sent out via the postfix-users list server. More importantly, however, in addition to verifying that you can connect to the host and complete a TLS handshake with s_client(1), you do need to post in the body of each problem report the new configuration you're using ("postconf -n" output as explained in http://www.postfix.org/DEBUG_README.html#mail) and logs of the associated problem behaviour. -- Viktor.
