The snowball effect becomes apparent. I report . Spammers don't follow the natural rules of emailing. The email then goes back to the person that sent it to you. Spammers rarely put their real email address as the return address on their messages.
Spammers also use techniques of using other internet services' email equipment to send their mail.
This has the effect of making it even more difficult to find who really sent the message. Sending hundreds or thousands of spam messages through that server will degrade its performance, thereby affecting the legitimate, paying customers. Net's newest mail servers, mail2.kearney.net , smtp.kearney.net , and pop3.kearney.net all have built-in protection against this activity. Make sure that your system is set up to take advantage of the new mail servers. Spamcop analyzes the spam message's headers and can accurately trace the mail back to its source no matter how clever the spammer is at covering his tracks.
