Since the spammer only "knows" me by my email address
and is unlikely to ba able to correlate the Host: values
reported by a browser with my email addr, I'm thinking
that Host: value isn't of much interest.  Further, if my
browser is behind a firewall that hostname is likely even
more useless to them.
