Hi all,

I have big problem with regular detecting of MPEG attachments based on
Filetype rules.

When I sent "PLAIN TEXT" e-mail with ISO-8859-2 encoding and first two
characters of body are "Vá" e.g. in Czech "Vá¾ený" (in English "Dear"),
then MS recognize him as "MPEG movie" !!! (log says "Filetype Checks: No
MPEG movies (42C121B907CA.60823 msg-24637-201.txt)").
If I write "space character" before "Vá", then everything is all right...

Any suggestions ?

Regards,

		Radislav.
