There is now #873065 on Postfix which suggests MTAs don't fall back to plain SMTP if the SSL handshake fails due to disabling of TLSv1.0 and TLSv1.1. I think this problem will be unsolvable before at least Google and Microsoft do the same on their inbound servers, forcing everyone to change configs. Bernhard
