North Star Techinical Services dislikes spam. It's wasteful and is near-worthless as a marketing strategy. Worst of all, it is annoying. No one likes to have their inbox filled with useless messages about products in which they have no interest.If we find that one of our clients is using our system to send junk mail, we ask them to stop. If they abuse our network a second time, they get disconnected. To date, none of our clients have misused our service. Our biggest problem is forgeries. People who are trying to be stealthy and clever seem to like using forged addresses like firstname.lastname@example.org or email@example.com. We usually can tell when someone has used such a forgery, because we get dozens of complaints about it. It is simple enough to explain to the complainants that the message did not originate here and is a forgery, but we do not like to stop there. We prefer to find out who originated the forgery and attempt to get them to stop. Should you ever receive junk mail containing references to mystery.com, please forward the entire message, including all of the headers, to firstname.lastname@example.org. If you are not familiar with message headers, they look something like this:

It also provides information about when the message was generated. Although much of this information can be forged, there is often enough valid information present to figure out where the message originated. By providing us with a complete copy of the junk mail, you help us track down who sent it. If we can find out who sent it, we have a chance of putting a stop to it. None of this is possible without your help.
