In this tutorial, we show you how to setup DMARC records in cPanel to specify how mail servers should handle messages from your domain that don’t have valid SPF and DKIM records setup. Since the DMARC standard is used by many email providers (such as Gmail, Yahoo!, AOL, Hotmail, Outlook), it increases your chances of email being delivered successfully. We provide basic DMARC record examples below.
DMARC Setup Steps
- Login to cPanel.
- Click Zone Editor under Domains.
- Click the Manage button next to the domain you want to work with.
- Click the +Add Record button.
- Change the Type from A to TXT.
- Enter the Name, TTL, Type, and Record as described below. Keep in mind that you must select one of the following options for the Record field: None, Reject, or Quarantine.
Field Setting Name _dmarc TTL 14400 Type TXT Record In this field you must choose how you want recipient servers to handle email from your domain that fails SPF/DKIM validation. Options are outlined below in red:
None:v=DMARC1; p=none; sp=none; rf=afrf; pct=100; ri=86400
Reject:v=DMARC1; p=reject; sp=none; rf=afrf; pct=100; ri=86400
Quarantine:v=DMARC1; p=quarantine; sp=none; rf=afrf; pct=100; ri=86400Alternately, you can request an email report of failed DMARC validations by adding a valid email address, such as the following:
None:
v=DMARC1; p=none; sp=none; ruf=mailto:[email protected]; rf=afrf; pct=100; ri=86400
Reject:v=DMARC1; p=reject; sp=none; rf=afrf; pct=100; ruf=mailto:[email protected]; ri=86400
Quarantine:v=DMARC1; p=quarantine; sp=none; ruf=mailto:[email protected]; rf=afrf; pct=100; ri=86400- Click Add Record to save your record.
Note: In Zone Editor, typing “_dmarc” will autopopulate the domain.
You will then see your record listed in the Zone Records section.
Congratulations, now you know how to setup DMARC records in your cPanel for email validation.

Thoughts on “How to Setup DMARC Records in cPanel”

- Click the Manage button next to the domain you want to work with.
I followed this guide but receive the following error:
Error:
[redacted].com’s “TXT” records have mismatched TTL values (900 and 14400). Records of the same name and type must always have the same TTL value.
Help!
According to cPanel “if a zone has any recordsets with mismatched TTLs, those mismatches must be fixed before the zone can be updated.” Due to this I recommend checking your TTL on any DMARC entries and ensuring that they are set the same. If your problems persist, our Live Support team can help review your DMARC records and enter them successfully.
Under what circumstances should one pick none, reject, or quarantine?
Keep in mind that this would only apply if an email from your domain fails SPF/DKIM validation. So if it is setup correctly it should not be a concern unless someone is spoofing your server/email accounts. This really boils down to preference, but here is a breakdown of the results you would get if an email from your domain failed validation:
I hope this helps.
yes it works for me and help me.
I don’t understand this comment:
Note: In Zone Editor, typing “_dmarc” will autopopulate the domain.
When I did this, it just expanded the first field to say:
_dmarc.[mydomain].com
but didn’t do anything else. Since that seemed wrong, I re-edited that field to
[mydomain].com.
and filled in the TXT contents from your other examples.
Hello Henry – thanks for your post about using “_dmarc” to autopopulate the domain. It is possible that current updates to the cPanel have changed the command. We are currently researching this and will update the article after confirming and needed change.
Nope, turns out the comment is 100% right after all. Type: _dmarc then tab out, and it will fill in _dmarc.yourdomain.com, which is totally correct. A number of tools apparently depend on the _dmarc prefix being there in order to do their jobs.
Thanks for the update, Henry. I’ll pass that along to the team.
Thank you so much its save my day…………
Glad it helped!
