DESCRIPTION

When reports are received, the XML is parsed into an Aggregate object, which then gets passed to the Report::Store and saved. When sending DMARC reports, data is extracted from the Store as an Aggregate object, exported as XML, and sent.

2013 Draft Description

The report SHOULD include the following data:

   o  Enough information for the report consumer to re-calculate DMARC
      disposition based on the published policy, message disposition, and
      SPF, DKIM, and identifier alignment results. {R12}

   o  Data for each sender subdomain separately from mail from the
      sender's organizational domain, even if no subdomain policy is
      applied. {R13}

   o  Sending and receiving domains {R17}

   o  The policy requested by the Domain Owner and the policy actually
      applied (if different) {R18}

   o  The number of successful authentications {R19}

   o  The counts of messages based on all messages received even if
      their delivery is ultimately blocked by other filtering agents {R20}

Aggregate reports are most useful when they all cover a common time period. By contrast, correlation of these reports from multiple generators when they cover incongruous time periods is difficult or impossible. Report generators SHOULD, wherever possible, adhere to hour boundaries for the reporting period they are using. For example, starting a per-day report at 00:00; starting per-hour reports at 00:00, 01:00, 02:00; et cetera. Report Generators using a 24-hour report period are strongly encouraged to begin that period at 00:00 UTC, regardless of local timezone or time of report production, in order to facilitate correlation.
