DMARC record or DMARC record is one of the important jobs and requires meticulousness. You can think of this record as creating a policy to filter emails. If the policy you create is incorrect, the biggest risk is that you will reject both valid emails and miss invalid emails. Therefore, please follow these steps carefully to avoid errors during configuration. Step 1: Create record Start by creating a record table as follows: _dmarc.domain.com TXT v=DMARC1; p=none; pct=100; rua=mailto:dmarc-reports@domain.com;. domain . com TXT v = DMARC1 ; p = none ; pct = 100 ; rua = mailto : dmarc - If you compare the record in the example above, you will see that the value “p=none” replaces “p=reject”. In particular, “none” will indicate that this is test mode. The receiving Mail Server will check each message sent but will only send reports without taking any action. Doing this helps us collect information about the mail server addresses sent to before deciding on appropriate action.

From there determine whether the result is fail or pass. In it, you need to pay attention to 3 important statistics. Processed : Number of messages sent to the report Fully Aligned : Number of messages that have passed both SPF and DKIM Failed : Number of failed messages at SPF or DKIM Continue, check the two fields Trusted sources and Unknown/Threats Trusted sources : Email server addresses including domain and IP have passed both SPF and DKIM. Unknown/Threats : Email server addresses that cannot pass SPF or DKIM. In many cases, Unknown are legitimate sources that are sending emails but do not include the use of DKIM or SPF .
Therefore, it will result in DMARC enforcement becoming extremely sensitive. Step 3: Pass all valid addresses for DMARC assignment After we have collected valid addresses, we will create a list for them and compare each new address with this list. The purpose of DMARC is ultimately to check the pass of both DKIM and SPF , in special cases such as email forwarding, where the Return-path is changed and SPF fails but DKIM is present, it is still considered a valid email. Step 4: Practical application The final step is to apply it in practice, once valid objects have been collected. Proceed to switch the record to a more strict “p=quarantine” monitoring mode. Emails sent in failed format will be moved to the Spam or Junk folder. Finally, we will set it to the strictest mode “p=reject”. The purpose is to ensure complete removal of all emails sent but failed.
