Why would this be useful to you? Let's say you need to sign up for many mailing lists using the same email address, and you want to be able to figure out which mailing list may have allowed your email address to fall into the hands of spammers. The solution is simple, sign into each mailing list with a unique identifier. For example, if you were to subscribe to the Speedbrake Publishing mailing list and you had the Gmail address your_name@gmail.com, join the list using your_name+speedbrake@
Try it yourself. If you have a Gmail account (if not, get one set up for free at Gmail.com), and then test it at the Speedbrake Publishing mailing list at http://subscribe.speedbrake.com with '+speedbrake' inserted before the '@' sign. After you finish the signup process, you will get a confirmation email. By the way, this confirmation email gives you a link to a free copy of my book Parenting and the Internet, which is a useful guide for managing the online affairs of your child.
Do this for all of your new mailing lists, using of course a different identifier for each, and if you start getting unsolicited emails, you can easily identify who did you wrong and take appropriate action.
