If you're using a bad email client (some versions of MS Outlook Express, etc) it can send a receipt w/o asking you. More commonly people will be talking about "Web bugs" (most often a 1x1 pixel GIF image with a name that's unique on the remote server, so they know that webbug/112312sdfsah1212.gif is '[EMAIL PROTECTED]'). A good mail client will not load images or plugins from remote servers and will not run any scripting information, protecting you from this problem too. Mozilla Mail is fairly good, but I don't know about how other clients for the Mac hold up in this regard. I use Evolution myself, which won't run on the Mac. Craig Ringer
