Amazingly this thread has moved in a totally strange direction (or I overlook s.th. and I make a fool of myself). The server does not advertise STARTTLS, so "command not implemented" is a correct response. You didn't have TLS enabled in the config you posted. You need to put "smtpd_tls_security_level = may" (or =encrypt) in main.cf or in the smtpd service definition in master.cf. You also need to configure the certificate and key files. See TLS_README in the postfix documentation. Rainer
