How to set up DMARC for Plesk in Valimail

Updated over a week ago
SPF(supported)
DKIM(recommended)

This article covers the SPF and DKIM authentication processes for Plesk and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Configuring DKIM authentication for your Plesk emails

  1. Go to Tools & Settings > Mail Server Settings > DKIM spam protection section.

  2. Enable the Allow signing outgoing mail or/and Verify incoming mail (For Plesk on Linux only) and press the OK button:

    • Verify incoming mail (Plesk for Linux)

      This option switches on DKIM checking for all incoming mail. All messages are checked, and if the check fails, are marked with a special header.

    • Allow signing outgoing mail

      This option enables customers to switch on the DKIM signing of outgoing mail on a per-domain basis.

      Warning: It does not automatically enable the signing of outgoing email messages. To use DKIM, users must switch it on for individual domains.
