I don't know how to do this with sendmail, but am I correct that your
sendmail will hand the message to your ISP via SMTP?  I don't think an
SMTP receiver normally generates Message-ID when it's missing, so this
may require special cooperation from your ISP.  Try telneting directly
to the SMTP server and sending yourself a test message without a
Message-ID to see if this will work at all.

As long as that machine never generates Message-IDs, and only one of
your internal machines does, there would be no problem in using the
router's hostname in your Message-IDs.  That would probably be the
easiest way, assuming you can tell sendmail to use that hostname for
Message-IDs.
