This looks a lot like the millions that were sent through one of my clients'
WAP.  If this is the case, it's nonroutable because they are sitting behind
a corporate firewall.

Now that is interesting.  The miscreant address 200.252.69.131 is apparently
an open proxy.  What is interesting about this message is the forgery of the
headers.  The 66.38.133.97 name is bogus, the spammer is using my mail
server's address as their hostname.  The 73.250.175.174 address is either a
deliberate forgery or an internal address of the open proxy, because it is a
non-routable address reserved by IANA.
Also note the bogus X-Mailer name.  The X-MS-Mail-Priority header on the
other hand, either gives away that the source was part of the Microsoft
Outlook family, or is another forgery.
Based on the number of ip4r tests the source address was in, plus the
COUNTRY routing, plus the obfuscation, plus the reply-to address, this
message easily reached my HOLD weight.  Which makes the effort to forge the
headers so remarkable!
