Your config contains TLS settings for inbound (stmpd_tls_...) but I don't see any TLS settings for outbound (smtp_tls_...). So it's nothing strange that TLS is not used for outbound connections. That's what you exactly told your Postfix to do. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
