in reply to Detecting an email address

Some pammers tend to place an img tag in the body of the email that really loads a cgi script that outputs a 1x1 jpg, with a creative url they can track mail messages opening and log RCPT TO: activity. It also helps us that like to track down spammers see where they really are coming from. =) so go for it.

    I think that can be considered an attack, and could cause the both of you trouble if put to a legal test.

    I think heavy consideration of the users' privacy, the lawfulness of such unpermitted entry, and the necessity of the act should be made before implementing.

    Of course, webbugs are easy to defeat if you've disabled all scripting in your email client (or it doesn't support HTML) and you've set your firewall to only allow it to connect to set mail servers on set ports (ie Outlook can only connect to ports 25 and 110 - all other access is blocked by my firewall: therefore webbugs on port 80 will fail).
