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?

Hi,
When you use readnotify.com you send your email to
user@domain.com.readnotify.com and it remails it to use@domain.com. From
what I remember readnotify.com remail your message and attach a web bug
i.e. an embedded image link. The image link is on one of their web servers
and this is used to identify when an email is read and for how long.

To foil it you can block loading images in HTML email. I'm not sure if
this covers the full extent of readnotify.com's tracking. You can get a
free trial of the service so you could sign up and send yourself some
messages.

Regards,
Jim Halfpenny
