Right, nmh doesn't have a way to generate a globally unique message
or content ID.  The default form is (and has been in MH), by way of
example:

    Message-ID: <address@hidden>

where the number portion is of the form pid.localtime in seconds since
the epoch, and the hostname portion is the local hostname.

Something based on the user's email address could help part way, but
only for the unique address of an individual.  I don't think this is
worth trying to fix.
