[Mimedefang] Blocking Missing Message-ID

[imacat]

Dear all,

    Hi.  I notice over 2/5 of my "remaining" spams are missing a
Message-ID, which is then added automatically by my sendmail MTA
afterwards.

    I'm thinking about blocking all the messages without a Message-ID,
that comes from unauthenticated clients in foreign networks?  Is this
dangerous?  Is it possible to block legal mails for this?
