I tell you, and you stop hijacking other people's threads. Deal?

readnotify.com is a so-called e-mail tracking service. Their subscribers
send their mail to them (by adding ".readnotify.com" to the recipient's
address) and they prepare a specially crafted mail from it and send it
to the recipient on the subscribers' behalf. In the default case the
tracking is done through HTML and webbugs. Have your mail clients
display plain text only and you'll be fine. Filters that catch webbugs
may help, too.

readnotify.com has a free trial offering, so you can toy with it
yourself.
