This confirms that Postfix never found the entry in your SMTP TLS policy table (otherwise it would have complained about "TLS1.2"). > > smtp_tls_protocols = !SSLv2,!TLSv1.2 > > smtp_tls_mandatory_protocols = !SSLv2,!TLSv1.2 > > This works fine for me.

However, the SMTP TLS policy table "lookup key" field needs to match the "next-hop" destination that is given to the Postfix SMTP client. If you override the destination with transport maps, per-sender relayhost, etc., then the "lookup key" field needs to match the override. Wietse
