Re: TLS 1.2 problem in Windows Azure

ALSO check the IP addresses in the log

The line
"SMTPC" 11532 2775 "2020-10-21 11:55:17.848" "200.1.116.12" "SENT: [nl]."
Is the last line shown for that message.

You can't completely block port 25 - all incoming mail comes via port 25

What we block is the ability to use Port 25 to AUTH

anyone who sends mail on my server must AUTH, and they must AUTH on another port eg 465 or 587, both of which are secured with a suitable certificate
