Because of the way MIMEDefang works, the filter_vrfy() may be called in
a completely different Perl process than the filter_helo() was, so you
still would need to pass the HELO information as a parameter if you
want to use it in filter_vrfy().

That's why filter_recipient() includes all the info in filter_sender(),
and filter_sender() includes all of filter_helo(), etc.
