We have a lot of outgoing mail every day. This all works fairly flawlessly.
unfortunately, there is 1 domain we can't send to. The error given in Queue viewer "451 4.4.0 DNS query failed. The error was: DNS query failed with error InfoNoRecords"
.
When I NSlookup the domain, our Mail server finds nothing. When I NSlookup from a domain computer or from a website like CentralOps, their domain and records seem to be working like normal.
Does anyone know why no DNS records for said domain can be found on our Mail server?
