Nonexistent recipients arrise for a number of reasons, number one being that some of our users did not supply their real email address. Number two is probably that some of our email addresses were submitted years ago and may not be valid any longer. Nonexistent sender addresses occur because the web server interface (third party software we did not develop) is seriously flawed and unfortunately upper management has determined that they have made too big of an investment in it to ditch at this point (other wise I would suggest eliminating it immediately) We only accept relays from our servers, all other emails are rejected. We are logging bounces as they occur to a database and removing problematic email addresses so that we do not send to them again. We are not "spammers", our bulk email is solicited. These are the reasons why we do not want to send a bounce notification email ever. First, because it wastes resources that we do not need to be wasting because of our bounce tracking system in place, second, because the web interface that generates the emails is very poorly designed and results in our attempt to deliver a bounce notification to bounce, which wastes more resources, third, because since no "human" should be using this machine a bounce notification would not even be useful.
