: Yes and no. First we need to know how they know you read your e-mail. I

: 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

Dan,
Wouldn't one need to know ALL of their server's names in order to be
sure
that they've blocked ALL routes back to www.readnotify.com ? I mean just
blocking http://www.readnotify.com isn't going to be enough, is it?
And how would one go about "blocking" their so-called "self-destructing"
E-Mails, or sender revocable E-Mails? As well as how would one go about
getting "around" their E-Mails that are suppose to prevent the recipient
from either forwarding, or printing out of an E-Mail?
