Clever Spam I Can’t Seem to Stop

I’ve been getting the following spam, one per day, over the past several months:

we email advertise your charity web site to 7,500,000 people. free.

I was receiving spam to the address I had on file with GoDaddy for my domain names, so I changed it, and included “nospam” in it, hoping that the spamming software would filter it out as being invalid. The very next day I was receiving spam to the new email address from this same spammer. Amazing. I know there are privacy options for domain registration, but it would cost me $500+ per year given the amount of domains I have, so it’s not really an option.

So what about local blocking of the spam? The problem is that the header is constructed in such a way that there’s no sender information whatsoever. Check this out (I’ve purposefully broken the email address used):

Outlook 2007 can’t spam block it because there’s no sender email address or domain. I also can’t create a rule because the email has to have a subject or sender. That IP address traces back to the Road Runner network, meaning it’s someone’s PC with a cable modem, likely infected by a bot and sending out spam without the user knowing (people like that should be blocked from accessing the Internet at all until they’ve fixed the problem).

Other than pressing the delete key, I’m out of ideas. I’m just thankful there aren’t more spammers out there doing this!
