mistress-kelly.com and barkenchirper.com both have ?all which should
NOT give pass, but neutral. So I guess the spammer is trying tricks
again to make people check for a pass Received-SPF header and give it
more weight not to be spam. The strange thing is I don't think ANYTHING
checks for Recieved-SPF headers and makes its less spam if they are
passes (But I could be wrong)
Only Baysian filtering might pick them up on some systems, so that's why
I strip all but the last one (added locally). If a host is not trusted,
the contents of the Received-SPF header are not really worthwile anyway,
as your example illustrates.
