Chapter 19      Email Authentication
  DMARC Verification
If you are using AsyncOS to perform DMARC verification and you have enabled sending of aggregate 
feedback reports in the mail flow policy, AsyncOS generates aggregate feedback reports daily, and sends 
it to the domain owners. These reports are in XML format and are archived into a GZip file. 
Note
All DMARC aggregate feedback reports that AsyncOS generates are DMARC compliant.
A DMARC aggregate feedback report contains the following sections:
Metadata of the report sender such as email address and report ID number.
Details of the published DMARC policy.
Details of DMARC policy disposition such as source IP address and disposition summary.
Domain identifiers
DMARC verification results and authentication summary.
