Yes and no. First we need to know how they know you read your e-mail. I common way is the use of a "Web bug" these usually consist of a small 1x1 image file usually the same color as the back ground of a html e-mail message or transparent. This method is easy and works on all platforms (Linux/mac/pc). If you use a mail client that doesn't auto download referenced images, then the the server hosting the image can't tell you have read the message. Read the provided wiki link for more on the subject.

Does anyone know anything about a web site called
(http://www.readnotify.com/)?  If so does anyone know of anyway to
prevent it from sending it's return receipts to the sender?
