Spammers are definitively improving: they now inform us, that the stuff they
send is Spam. A message I just received looked suspicious: it wasn’t caught by
our spam scanners, but it certainly wasn’t intended for me. The subject begins
*SPAM*, and that isn’t what we modify subject headers to when our
scanners identify Spam. Looking closer, the message’s headers contain:
X-cff-LastScanner: footer X-cff-SpamScore: 5 (+++++)
Those are definitely not added by our systems. In other words, the PDF junk sent by that firm was marked as junk when it left their doorstep. Is it time to downscale the spam-filtering systems we drive? Unfortunately, not yet.
