Which says nothing about if it's forged or not. There is no requirement for
mail to be sent from the same IP address as their web server. By your logic
this message I'm typing now is forged.
You are correct though about 220.127.116.11.
The simple solution is for people who get these delivered to their inbox to
report them to Spamcop. This kind of backscatter is considered reportable
spam. If your mail provider uses the Spamcop RBL, once it's one the RBL you
won't see it any more. Also, that will likely affect enough mail to get the
attention of the admins of that server.
