Really, you want to look at mhn.defaults. That's what nmh uses, and that

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.
