[nznog] Bizarre spam

I've got a question for the appropriate higher minds. I fixed one of my clients self-built contact forms after I had an inkling that someone was injecting headers into it to use it as a relay. Turns out I was right, but it's beyond me what they're trying to accomplish: Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: which a rising moon now threw from the scattered clouds bcc: charleslegbe(a)aol.com 648a4d46b041327ac30fe4f27a9b72ee . Tons and tons of that just that. What possible use could this garbage be? Is someone trying to blackhole their domain? Cheers Justin
