mhtxthtml.pl filter modified to reject any message with
nested tags.  This is invalid HTML, so any message
that contains it would likely indicate someone trying
to attack an archive web site.

Specially crafted HTML email message can allow scripting
content to make it passed the default HTML MIME filter,
allowing for XSS-based attack on archive site.
