mrmaxx Posted August 9, 2013 Share Posted August 9, 2013 Had a problem at work here for about a half hour where I couldn't send emails outside of the company because our domain name was not able to be resolved. I even tried looking us up at SpamCop by putting in the domain name of the company (which shall remain nameless) in the spam reporting window. As a result, all my emails outside the company and incoming from outside bounced. That got me to wondering about the whole DNS-based anti-spam system. Did anyone envision what would happen if a sender's DNS got FUBARed somehow so that the domain name of the sender was no longer resolveable? The practical effect seems to be that the sender's email gets rejected by the receiving server, which, to me, would not necessarily be the best practice. That being said, I've always said that email was never designed to be a guaranteed message delivery system, despite all the add-ons such as delivery confirmation or "read receipts" etc. Link to comment Share on other sites More sharing options...
