As I understand it, these directions would force our Exchange (Edge) server to do an external DNS lookup vs our internal DNS server. Any internal email on the exchange server should still remain unaffected? This should only cause externally destined emails to perform the lookup on external DNS servers?
As I understand it, the function of DNSSEC is to ensure the validity of the resolved host. So making this change ensures that Exchange will use the correct/secure MX record for the destination domain. Since this requires a reboot, I am cautious of making any changes when sending to other domains is not having a problem. Thanks for the input! Eric On Thu, Aug 16, 2012 at 8:40 PM, Michael B.
