: Hey Hey,
: 
: ReadNotify (for standard emails) using 1x1 tracking to follow your
: message... it inserts a 1 pixel by 1 pixel image into the HTML of the
: email (If you're using Outlook for example, right click and go to View
: Source), you'll see the location to that image. When this image is
: accessed, the email is considered read. (so for example
: hfebelingjr () lycos com readnotify com) would ask you to send a read
receipt
: and you would say no... but then if your mail viewer retrieved images by
: default, the user would still receive a read receipt.
: 
: There is also the option of sending an email to
: hfebelingjr () lycos com silent readnotify com in this case when you open
it,
: you will not be asked to send a read receipt but if you tell it to
: download images... it will notify the user that it has been read...
: 
: Best way to disable/prevent it... don't download images on your emails...
: You can check your message headers (if it's not silent... and you do get
a
: read receipt request and you'll see X-Read-Notification: Courtesy of
: ReadNotify.com - http://www.<garbage>.readnotify.com) With the silent
one,
: you have to look at the source... The following code is added to the
: email.

HT,

        No problem about the rambling, I am interested in learning all that I can
about computers and right now about (www.readnotify.com) and how to defeat
it.  Does readnotify appear in the headers in any form if an E-Mail is sent
"silent?"  As I said (I think) in my reply to Jim, I presume that IF one
saves an E-Mail as a text document without opening it, that one can then
read it's content WITHOUT "tripping" the embedded image?

        I've already scanned the headers and saw the readnotify.com reference in
'em.  Which I guess it's a good thing that I know how to read headers,
which is how I found out about readnotify.
