$sender_host_address will be unset for messages that do not originate
from a remote host. Since you are checking for a protocol of
"spam-scanned", I assume this message has been re-injected from a spam
scanner running on the local host. Hence, the message has not come from
a remote host.
What you could do is to pass $sender_host_address to your spam scanner,
and have it pass it back using -oMa.
