This stuff basically looks to me like a typical pattern of header
forgeries common to a lot of spamware (to a great extent, everything
that can be forged is forged). The nice thing, though, is that all the
stuff is showing up with sender addresses in the optingnow.com domain,
making it quite easy to block. I got my first report of this spam last
week so fortunately I've seen a lot of rejections since then rather than
a lot of spams.
This does underline just how bad the open HTTP proxy problem is right
now, and that it's likely to get worse. Open proxies are also much more
than a spam problem, as they generally allow effectively anonymous
connections to any TCP service.
