Easy to do if you don't defang web bugs. My hypotheses is as follows. Spammer sends you a spam with web bugs. You view the spam and images with tracking code are loaded from the spammers web server. They have then your ip address. Spammer then sends fake opt-in confirmations with your ip address automatically.
Check out the Sanitizer* http://www.impsec.org/email-tools/procmail-security.html See the http://www.impsec.org/email-tools/procmail-security.html for a list of the possible attacks which the sanitizer generally foils. Best of all it's free. *I am not the author or associated with the software in question. Just a very happy user of it. ----- Original Message ----- From: "Steve Prior" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, March 02, 2004 10:13 PM Subject: Spam opt in confirmations with my IP address? > Today I've received 2 opt in confirmation emails which claim that I opted in > to their spam, but the kicker is that both emails show the IP address that they > claim the opt in came from and it really is my IP address!
