[SpamCop-List] No source IP address found

[Alan Harper]

I am getting spam sent to an email address that is (currently) not
being filtered by Spamcop.

When submitted to spamcop parsing, I get the following:

The headers start with these lines:

I am confused because the first Received line has an IP and a name that
don't appear to correspond to each other. Can Received lines now be
forged? Or is SBC/Yahoo somehow munging the headers in some misguided
fashion?
