Well, that depends.  If your nmh was configured with a mimetypeproc,
then that will be tried first.  See the paragraph containing
Content-Type in the send(1) man page.  My nmh build shows:

    $ mhparam mimetypeproc
    file --brief --dereference --mime-type

So, it tries to use that file(1) command before falling back to
mhn.defaults.  Implementation details are in m4/mimetype.m4 and
sbr/mime_type.[hc].

With that file command, you can add custom entries to a ~/.magic file,
though I have not had to do that for a long time.
