It varies from one e-mail program to another, leeneia. I have Hotmail, and I can click on the bar at the top of the e-mail to get more information about the sender. If I right-click on the title of the e-mail in the list of e-mail messages in Hotmail, I can choose "view message source," and that will give me full information.

999, this problem seems to exist with all the major web-based e-mail providers - yahoo, gmail, hotmail, etc.
