I have a firstline / graveyard system of Postfix. So, one server is the graveyard of the first line server. I managed this by setting the smtp_fallback_relay in the first line server.

So far, so good, the graveyard receives the emails rejected from the first, but I don't know why, it changes the original message-id of the message. Basically, it makes up a new message-id based on the date and hour, if I'm not wrong.

That's bad, because I'd like to keep track of the messages through this parameter.

You will need to show proof that this happens.

I suspect you're confusing the SMTP Message-Id: header with the postfix Queue-ID.
