[SOLVED] Deferred Emails
All our emails have been deferred since 8:00AM PST. Normally I can fix this by a flush and restart. However, I also requeued and disabled greylisting. This has not fixed the problem. All 250+ messages are still deferred.
It's saying: delivery temporarily suspended. host or domain name not found...
When I unchecked DNS lookups in the Global settings, we started receiving emails. What I am wondering is what triggerred the emails to start deferring.
By unchecking DNS lookups, we are now unable to send emails..

The DNS was incorrectly assigned.
