Okay I am trying to troubleshoot a failure with an APC NMC 2 card. Their KB article points out that it has trouble with snmp an it needs to be able to lookup the mx record. Here is a clip from the Kb explaining the resolution.
"Pursue caching the MX Record for your selected SMTP server on the DNS server (or use a DNS server that has the record cached)"
So..... my question is how do i cache the mx record? We use office 365 so the server is smtp.office365.com. I have a windows DNS server. So do I need to create a forward lookup zone for smtp.office365.com and then create an MX record for the same thing?
