Adding a footer to email if sent via TLS.

Tony Kilbarger

Our legal folks have asked if it is possible to add a footer to outbound email if it went out via TLS.  So if it successfully negotiates TLS, can we add a footer that says "Sent successfully via TLS 1.2".  Is this possible?  It would seem too late to add add after the connection is made.

Hi Tony,

 

you are correct and once the connection is established and the mail is sent, there is no way to add a disclaimer.

 

What about the approach of adding a TLS encrypted footer to all messages, enforce TLS encrypted for all outbound domains/connections and return the messages to the sender where secure TLS is not possible ? - Then you can remove your footer again and tell them NO TLS was possible...
