I believe it has to be a *syntactically* valid email address,
according to the RFC. So, for example, an all-alphabetical random
string would fail, because it'd lack a "@".

I myself see not much wrong with a mailing list doing that, but:
- others seem to feel differently, that modifying the msgid once a
valid one has been generated by a MUA is gauche. And I understand
that it makes some things slightly harder, especially if you use fcc
or similar feature in other MUAs.
- if the mailing list does mess with msgid, it absolutely must do it
consistently for all copies of the message. Not like the mailman
managed GNU lists where the msgid was (or still is?) munged if and
only if the message was crossing a mail / news boundary. I stopped
following the GNU lists because of that and I never went back.
