Postfix TLS Support When the TLS handshake fails for an opportunistic TLS session, rather than give up on mail delivery, the Postfix SMTP client retries the transaction with TLS disabled. Trying an unencrypted connection makes it possible to deliver mail to sites with non-interoperable server TLS implementations. Enable Transport Layer Security (TLS) 1.2 overview This negotiated version is the one that is used for the connection. If the server doesn't support the version presented by the client, the server message will specify the highest version it can use.
