How to enable DMARC for incoming mail in Plesk?
DMARC for incoming mail is available since Plesk Onyx 17.5. To enable it:
- Go to Tools & Settings > Mail Server Settings (in the Mail group). The server-wide mail preferences screen will open on the Settings tab.
- In the DMARC section, select the Enable DMARC to check incoming mail checkbox. On a Linux-based server, this option is available only when DKIM and SPF are enabled for incoming mail.
Note: enabling this feature can cause inability to send internal mail between mailboxes of the same domain hosted on Plesk server.
