Has anyone else seen this error? Is it caused by Ironmail SMTPO not being able to connect to the listed DNS servers? I've raised a ticket with McAfee but was wondering if anyone else has seen this error.
Previous version on Ironmail did not failover to the secondary DNS, when the primary one failed or was down. You may want to test connectivity to the DNS via CLI.
If one is reachable, make sure its the first one in your entry.
