OK, look. I guess I need to spell it out for you. End-user PC has virus. Virus does this: telnet isps-smtp-server 25 HELO bogus MAIL FROM:<[EMAIL PROTECTED]> RCPT TO:<[EMAIL PROTECTED]> DATA . Then ISP's mail server does this: telnet victims-smtp-server 25 HELO isps-smtp-server MAIL FROM:<[EMAIL PROTECTED]> RCPT TO:<[EMAIL PROTECTED]> DATA . If victim's SMTP server fails the DATA with a 5xx code, then backscatter goes [EMAIL PROTECTED] Understand now?
