How are dmarc records implemented?

Here are the steps you need to take to implement a DMARC record:

  • Use the following syntax in the DMARC TXT record:

What is a dmarc record?

A DMARC record is the record where the DMARC rulesets are defined. Once SPF and DKIM are in place, you configure DMARC by adding policies to your domain’s DNS records in the form of TXT records (just like with SPF or DKIM). The TXT record name should be “_dmarc.yourdomain.com.”

That’s because DMARC requires the SPF and DKIM addresses to be “aligned” with the human-readable From address — an important step if you’re going to prevent fraud. As part of evaluating whether an email message passes SPF authentication, a receiving mail server may have to make one or more DNS lookups.

What is a dmarc record in DNS?

This DMARC record informs email receivers if a domain is set up for DMARC. If so, the DMARC record contains the policy which the domain owner wants to use. In essence, a DMARC record a DNS (Domain Name Service) entry. One can start using DMARC by implementing a DMARC DNS record.

What is a dmarc location?

Demarcation point is sometimes abbreviated as demarc, DMARC, or similar. The term MPOE (minimum or main point of entry) is synonymous, with the added implication that it occurs as soon as possible upon entering the customer premises. A network interface device often serves as the demarcation point.

What is the difference between DKIM and dmarc?

DMARC enables the message sender to indicate that their messages are protected with SPF and/or DKIM. A DMARC policy applies clear instructions for the message receiver to follow if an email does not pass SPF or DKIM authentication—for instance, reject or junk it.
