Is there any way of filtering out unknown charsets as in the examples below:-
----A936ADD5A146DE8ECF3
Content-Type: text/plain;
charset="iso-61FC-B"
Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain;
charset="iso-8FCB-F"
Content-Transfer-Encoding: quoted-printable
Lately we have receiving spam with randon generated iso- ????? sets.
Thanks
