You define Domain-based Message Authentication, Reporting, and Conformance (DMARC) functionality by entering a DMARC record in your domain’s DNS settings.
After preparing the text of your DMARC record, add or update the DNS TXT record at your domain provider. To update a DNS TXT record, enter the line of text that defines your DMARC policy record in the management console for your domain provider.
Every time you change your DMARC policy and update your record, you must update the DNS TXT record at your domain provider.
Add or update your record
Configure DomainKeys Identified Mail (DKIM) and Sender Policy Framework (SPF) before configuring DMARC. DKIM and SPF should be authenticating messages for at least 48 hours before turning on DMARC.
The domains used in the steps below are examples only. Replace these example domains with your own domains.
Do these steps in the management console for your domain host, not in the Admin console.
Have the text file or line that represents your policy record ready.
Sign in to the management console for your domain host.
Locate the page where you update DNS records.
Add a DNS TXT record, or modify an existing record, by entering your record in the TXT record for _dmarc:
TXT record name: In the first field, under the DNS Host name, enter: _dmarc.solarmora.com
Important: Some domain hosts automatically add the domain name after _dmarc. After you add the TXT record, you can verify the DMARC TXT record name to make sure it's formatted correctly.
TXT record value: In the second field, enter the text for your DMARC record, for example:
v=DMARC1; p=none; rua=mailto:dmarc-reports@solarmora.com
The field names might be different for your provider. DNS TXT record field names can vary slightly from provider to provider. The domain used here is an example domain. Replace solarmora.com with your own domain.
Save your changes.
