    Two minor nits:

(1) You should use the "application/octet-stream" media type for unknown
    attachments instead of "APPLICATION/xx" (RFC 2046);

(2) According to RFC 2183, the filename part belongs in a separate
    "Content-Disposition:" header, not in the "Content-Type:" (although
    Pine and some versions of Emacs perpetuate the old syntax).  Any
    decent MIME-capable mailer should be able to find the filename in
    both cases.  See also RFC 2112.

    Consequently, you should replace

        echo "Content-Type: APPLICATION/xx; name=\"$MATCH\"";\

above by something like

        echo "Content-Type: application/octet-stream";\
        echo "Content-Disposition: attachment; filename=\"$MATCH\"";\
