How do you configure DMARC in the Ironport Email Security Appliance? I have it on but according to other sites it seems more complicated then 'flipping a switch'. I mean sites say you should have a TXT dns record, and then there are also third parties like dmarcian.com to "subscribe to".
Also most say there is an email address for "reports". Is this something I would have to create in Exchange, or is this something the IronPort would handle if I enter a fake email address in the DMARC policy and then put that same address in a DNS TXT record. Would IronPort get these dmarc reports and process them internally without end user intervention?
Following this wizzard here to create a DMARC TXT DNS record: https://www.unlocktheinbox.com/dmarcwizard/ What would I put for Aggrigate Email RUA or Forensic Email RUF? What about report format? Is it required to subscribe to a third party thing?
