How to enable DMARC in Plesk?
The DMARC feature is available starting from Plesk Onyx 17.5.
Note: MailEnable mail server does not support DMARC feature. For more information about DMARC protection, visit this Plesk documentation page.
In Plesk go to Tools & Settings > Mail Server Settings.
On the Mail Server Settings page, scroll down to the DMARC section and enable the option Enable DMARC to check incoming mail.
On Linux servers, DMARC feature requires DKIM and SPF to be enabled.
- Click OK to apply the changes.
If the DMARC feature is enabled, but the DMARC record is missing in DNS settings of a domain, add it using the below steps:
In Plesk, go to Domains > example.com > DNS Settings.
Add a new record:
PLESK_INFO: Record type: TXT
Domain name: _dmarc
TXT record: v=DMARC1; p=none
Note: Enabling DMARC feature may cause the issue where emails between mailboxes of the same domain will be rejected.
