Hi there,

I've added 2 new nodes to PMG Cluster, but, they both have the same error when receiving our email to relay out:

Code:
status=deferred (address resolver failure)
451 4.3.0 <name@example.com>: Temporary lookup failure;

We are using Unbound and its working fine:

Code:
root@node9:~# dig gogole.com @127.0.0.1 +short
216.58.201.100

Do you have any ideas?

Thanks! :)
 
anything in the unbound logs that might indicate what the issue was at that time?
