You may want to use the "usenameext" option instead.

Subdirectories are only created when attachments exist and the
"subdir" option is specified (assuming the m2h_external::filter
is being used).

As for the browser issue, that is outside of MHonArc's realm.

Yep.  And the doc warns about this.

Here is the problem.  From the MIMEARGS resource page:

    If an argument string is defined for a filter explicitly and for a
    content-type that the filter processes, the content-type string
    will override the filter string.
         ^^^^^^^^

In your case, the options for application/msword take precedence
(and does *NOT* augment the filter options).  So, msword data will always
be put in the same directory as the message while all other attachments
will go in a sub-directory.

Add the "subdir" option to application/msword.

P.S.  Please avoid sending HTML messages unless absolutely necessary.
We try to advocate proper use of MIME on this list.  Thanks.
