Hi all, In one of my tests I'm configuring Postfix client (smtp) to use opportunistic TLS with TLSv1.2 protocol only and the next MTA (server side) to use opportunistic TLS with TLSv1.1 only, to see the behaviour of Postfix after a failed handshake. As expected the TLS handshake fails, but Postfix moves the message to deferred queue rather than retrying immediately in plaintext.
What is the reason of the timeout between the incoming_arrival and active_arrival (var_min_backoff_time) of a message, before the message is allowed to be immediately retransmitted?
