Rather than manually discovering and maintaining a list of domains
that refuse null senders, you might be able to use a dnsdb call
to dsn.rfc-ignorant.org. (see http://www.rfc-ignorant.org/policy-dsn.php )

e.g. something like

if ("${lookup dnsdb{a=${sender_address_domain}.dsn.rfc-ignorant.org}{$value}}"
is not "")
