How to Create a DMARC Record
A DMARC record is used to protect against email spoofing. It is a TXT record that is included in the DNS record for a domain. What to do with messages that fail or pass DMARC authentication is specified in the DMARC record for receiving mail servers. In this article, we will be discussing steps to create a DMARC record.
Steps to create a DMARC record
Step 1: Identify your business email domain
Determine the email address from which you send commercial emails. The domain is mycompany.com, for instance, if you send sales emails to potential customers at email@example.com.
Step 2: Generate a DMARC record
Create a Skysnag account to generate your DMARC record.
Step 3: Add the DMARC record to your DNS
Copy the DMARC record from the Skysnag dashboard, then add it to your DNS records.
Step 4 Verify the DMARC record
After you have added the DMARC record to your DNS, please verify using the Skysnag dashboard.
The DMARC record is added to your DNS zone file in the following format:
_dmarc.example.com IN TXT “v=DMARC1; p=reject; rua=mailto:firstname.lastname@example.org”
The DMARC record contains the following parameters:
v=DMARC1 – The version of DMARC.
p=reject – The policy for messages that fail DMARC authentication.
rua=mailto:email@example.com – The email address to which aggregate reports are sent.
The DMARC record can also contain the following parameters:
|The percentage of messages to which the DMARC policy is applied.
|The policy for messages that pass SPF authentication.
|The policy for messages that fail SPF authentication.
|The email address to which failure reports are sent.
|The format of failure reports.
|The interval at which aggregate reports are sent.
|The alignment mode for DKIM.
|The policy for subdomains.
|The alignment mode for SPF.
