Please be aware that port 465 "smtps", or as some mail clients call it SSL, was never accepted as a standard and is deprecated. You should use the submission port 587 instead, as it is designed for this purpose. That said, some legacy clients require port 465 smtps. To enable it, smtps requires '-o smtpd_tls_wrappermode=yes" option on the smtps service in master.cf. See the wrappermode discussion in this section: http://www.postfix.org/TLS_README.html#server_enable But you should really be using the "submission" service instead. If your postfix is trying to *send* mail using smtps, please see this: http://www.postfix.org/TLS_README.html#client_smtps But you should really be using the "submission" service instead. -- Noel Jones
