I'm having an issue sending e-mails to domain capitaliii.com from my Ironport. I see the following message in the Ironport log.
"DNS Temporary Failure capitaliii.com MX - unable to reach nameserver on any valid IP"
When I issue a nslookup on the MX record from the Ironport, I get the below message.
Temporary query error: "unable to reach nameserver on any valid IP" looking up A record for "capitaliii.com" to nameserver
I can however do a successful a successful nslookup from my workstation. See the results below. Any ideas? I've done
a flushdns on the Ironport to no avail.
capitaliii.com MX preference = 10, mail exchanger = mail1.digipark.commail1.digipark.com internet address = 18.104.22.168
I have this problem too.
