Spam Without Headers

Donncha O Caoimh wrote in to tell us about the RFMS spam mail server. It is $700 (!!) and ships out email in bulk. This is the kind of stuff that really burns my bottom. Not only is this company violating SMTP standard to send email nobody wants, but they are charging an amazing amount of money to do it. I don't really know how to handle this. Perhaps we should spam their 888 number. I don't have a problem with spam sent with a valid header- I can filter that, but this is exactly what is wrong with the 'net. Companies like this must be stopped. I'm waiting to hear everyone's suggestions, but there has got to be something legal that the thousands of Slashdot readers can do to make this kind of thing stop.
