OK, I would likely accept a patch to fix that.

A note about Message-ID uniqueness...  The v2 code will generate
a new, truly unique Message-ID on duplicates and use that in
msgmap instead what was in the message.  It's gross, but I needed
to do that to allow all messages to be accessible via Message-ID
over NNTP, because:

a) some legit messages reuse Message-IDs :<

b) some broken mailers (including some versions of git-send-email)
   put multiple Message-IDs in the same message, so the code
   needs to handle messages with any number of Message-IDs
   anyways.
