It means no TLS protocol actually took place. The sender gave up.
This is basically:
Sender: "I notice we are speaking English, may I switch to Greek?"
Postfix: "Go ahead my Greek translation unit is on line now!"
Sender: Hangs up the phone, before sending a word of Greek, or anything
else.
If you ponder this for a moment, you can conclude that neither the
Postfix use of the Greek translation unit, nor the internals of that
unit can possibly contribute to this problem, as no Greek is ever spoken.
The sender changed his mind about continuing the conversation. Why?
Only the sender can tell, unless what you see is a fiction, created by
some intermediate firewall.
