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

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?
