Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Depending on the DMARC verification result and the specified DMARC verification profile, 
AsyncOS accepts, quarantines, or rejects the message. If the message is not rejected due to DMARC 
verification failure, AsyncOS continues processing.

AsyncOS sends an appropriate SMTP response and continues processing.

If sending of aggregate reports is enabled, AsyncOS gathers DMARC verification data and includes 
it in the daily report sent to the domain owners. For more information about the DMARC aggregate 
feedback report, see 

.

If the aggregate report size exceeds 10 MB or the size specified in the RUA tag of the 
DMARC record, AsyncOS sends delivery error reports to the domain owners.

A DMARC verification profile is a list of parameters that the mail flow policies of the Email Security 
appliance use for verifying DMARC. For example, you may want to create a stringent profile that rejects 
all non-compliant messages from a particular domain and a less stringent profile that quarantines all 
non-compliant messages from another domain.

A DMARC verification profile consists of the following information:

A name for the verification profile.

Message action to take when the policy in the DMARC record is reject.

Message action to take when the policy in the DMARC record is quarantine.

Message action in case of a temporary failure.

Message action in case of a permanent failure.

Create a new DMARC verification profile or 
modify the default DMARC verification profile 
to meet your requirements.

(Optional) Configure global DMARC settings 
to meet your requirements. 

Configure your mail flow policies to verify 
incoming messages using DMARC.

(Optional) Configure a return address for
