OK.  We feel your pain. ;)

I'd use a slightly modified version of Joseph Brennan's suggestion:

sub filter {
	my($entity, $fname, $ext, $type) = @_;

        if ($type !~ /^text\//i) {
		action_replace_with_warning('This part has been removed');
        }
}

NOTE: This sure looks safe, but I bet that Microsoft Windows will happily
run a text/plain part called "gotcha.exe".  Such is life with Windoze.

Regards,

David.
