How to properly remove the Message-ID header in outgoing exchange 2013?

Question

Mail server

There is Exchange 2013 CU10. One single, with all available roles. There is a task - to prohibit the mention of the internal name of the server in the headers (well, such a whim among people). Ok, an article about headers firewall is being googled, permissions to the send connector are being removed. There are Message-ID headers, but they can be removed simply through transport rules.
And now attention, magic. If I write a test letter to myself on gmail with a filled in subject and message text, everything is fine: "[email protected]" is written in the Message-ID field and everything is bugged.
But if I send a letter with only the subject of the letter, but without the text, then, firstly, the Message-ID header is placed significantly lower than its usual location, after not regular, but artificially added headers. And in it, damn it, native messadzhaydi. And this is with the rule "remove Message ID headers if the sender is a Test Test Testovich" running.
An empty topic, but the text is there - everything is ok. There is no text, but there is an attachment - everything is still bad and the Message-ID remains as if there is no rule.
What is the jamb? Am I doing something wrong or is it not working somehow?

Answer 1

Message-ID is a mandatory header, you can't remove it, as this will lead to the fact that your emails will be triggered more often by the anti-spam filter. In your example, the Message-ID was added by the recipient's server (mx.google.com), this is a fairly common practice, because otherwise the letter cannot be considered correct. Even if you put some kind of filter that will change the Message-ID along the way, this will lead to incorrect formation of email chains, because The Message-ID is used to build the In-Reply-To header.
