Intermittent outbound email. What is the meaning of the following NDR
Posted on 2008-06-18
Our DNS records got moved to a new dns server and the person running the old dns deleted all our old records. A whois shows the correct info but outbound email does not seem to be working properly it is intermittent. We get the following NDR when we try to send to most domains.
the following recipient(s) could not be reached:

<caamb8.caamanitoba.com #5.7.1 smtp;554 5.7.1 This message has been blocked because the return email domain is invalid.(failed to obtain DNS record for domain caamanitoba.com)>
I don't see how this can have anything to do with outbound email. I can see how inbound email would not work for a few days but outbound should be fine. Can someone tell me what that NDR really means. THanks in advance
