Recommendation or rule?  I don't recall.

The reason you state seems precise rather than vague.

The first-hop MTAs would be a source of prior art.  Most probably let
the domain part be given as configuration.

I think the existing -messageid option which takes either ‘local’ or
‘random’ should also accept ‘@...’ to allow the user to specify it.
This stops using heuristics if the user prefers.

Instead of having to state that as a default option in the profile for
multiple programs, a new profile component, ‘message-id-domain’, could
let it be set once.  If it is set then -msgid is implied.
