9.10 Configuring DMARC
MailMarshal can participate in DMARC for local domains you specify. DMARC relies on SPF and DKIM. For an overview of all required configuration, see Trustwave Knowledgebase article Q20650.
To use DMARC, you must set up information for one or more local domains and then enable DMARC for each domain. You can then choose to configure Content Analysis rules to take action on incoming messages depending on the results of DMARC validation.

Important: Enabling DMARC for a local domain causes DMARC validation and reporting to be performed for all messages addressed to the domain, as well as including the required DMARC information with each message sent from the domain through MailMarshal. This behavior is required by the DMARC framework. |
To configure DMARC for a local domain:
1.In the left pane of the Management Console click System Configuration.
2.In the right pane, click Local Domains. Select a domain, and then click Edit.
1.Click the DMARC tab.
2.Ensure that a DMARC DNS record has been found and displayed. If a record does not display, investigate further that the record does exist and will be propagated to public DNS.
3.Select Enable DMARC.
4.Configure and enable rules to apply DMARC policy and accept DMARC reports. Rules are included in the default rules for new installations, and in a special policy group that is created on upgrade.
You can review DMARC results by sending DMARC report email to a third party site.
