I have not seen such behavior in the past 20 years...
Ok. I stand corrected then. What about bounces? Don't they
intentionally keep all of the same headers with an empty envelope-from?
Answering myself. No. I checked a few and the Message-ID is generated
new on bounces too. NM Ignore me ... :) I was thinking of something
else related to email archiving that dedupes based on the Message-ID.
Happy New Year!
Intentionally re-using another site's MIDs is so wrong that I'd
happily make it break hard.
HOWEVER, the idea of enforcing any standard on MIDs beyond gross
format (e.g.: <[[:ascii:]]{3,996}>) on a system where the admin isn't
the sole user is ludicrous.
