We can recive mails from that domain but we can't send to it. Remote Server returned '< #4.4.3 X-Spam-Firewall; Host or domain name not found. Name service error for name=somedomain.com =MX: Host not found, try again>' firmware version is 7.0.0.004 on the recpitient https://community.barracudanetworks.com/forum/index.php?/topic/27783-443-x-spam-firewall-host-or-domain-name-not-found/ site are 5 name servers and 2 of them are offline. I have checked MX records with mxtoolbox.com and seems they are ok I can't find any configuration in admin web gui. only thing I found is 'Enable Direct DNS Queries:' and is set to 'no' please help. Back to top #2 Barry van Hattum Barry van Hattum Members 22 posts Posted 29 March 2016 - 03:38 AM Hi John, This means the Barracuda cannot resolve the domainname. This is most likely not a Barracuda issue. Can you verify tht the DNS server being used by the Barracuda is able to resolve the domainname. You can check the resolving by going to "Advanced" -> "Troubleshooting" and using the Dig/NS lookup field. You can also try a tcpdump from there is you want. This problem is likely caused by the DNS server used by the Barracuda. IT is not able to resolve the domainname to tell teh Barracuda where to send the email to. Hope this helps.
