I'm better when writing in french :-)

What I would like is no Message-Id at all when the message is sent to the
firewall.

Before stripping it in header_checks the message included the client's
hostname.

After stripping the message includes the server's hostname.

That's much better, as only one hostname appears in all Message-Ids, but it's
not quite what I would like.
