Both were included in original mail. Here is one that works, as it spells
out the filename in what looks like a UTF-8 encoding of 2-bytes for each
character:

--------------080904060007010807050604
Content-Type: application/msword;
name*=ISO-8859-7''%C4%EF%EA%E9%EC%E1%F3%F4%E9%EA%FC%E1%F1%F7%E5.doc
Content-Transfer-Encoding: base64
Content-Disposition: inline;
filename*=ISO-8859-7''%C4%EF%EA%E9%EC%E1%F3%F4%E9%EA%FC%E1%F1%F7%E5.doc

And here is one that does not work, since it requires deconding from IE,
which does not recognize the encoding specifier:

--=_3z1haj6nfrs4
Content-Type: application/msword;
        name="=?iso-8859-7?b?5O/q6ezh8/Tp6vzh8ffl3+8uZG9j?="
Content-Disposition: attachment;
        filename="=?iso-8859-7?b?5O/q6ezh8/Tp6vzh8ffl3+8uZG9j?="
Content-Transfer-Encoding: base64

Thanks.
