How do I create or edit a DMARC record?

DMARC stands for Domain-based Message Authentication, Reporting and Conformance. It's a way to tell the Internet what they should do if they get an email from your domain that seems suspicious.

A message will be considered suspicious if it fails either your DKIM signature test or your SPF test.

You must create DKIM and SPF records before you create a DMARC record.

Your doman's DMARC setting only affects email sent from your domain. It has no impact on the amount of spam that you may be receiving.

In addition, setting DMARC record may help messages sent from your domain avoid the spam folder, since some email providers seem to be punishing email senders who do not have a DMARC policy set.

If you want help setting up your DMARC records, please email or call support. It can be tricky and we are here to help.

v=DMARC1; p=quarantine;

This setting takes most of the default values. It also tells the world that if an email message fails the test, send an email and quarantine the message (that usually means send it to the user's spam folder). Alternatively, you can specify that it should "reject" the message.

To begin, you must edit your Domain Name records - To make the change, you must edit your domain's DNS records. PTP does not have access to these records and cannot do it for you.

How you edit these records varies depending on where you Internet services are hosted. For example, if you are hosted with:
