How to enable DKIM (spam protection)  in Plesk?

  1. Log into Plesk.

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

  3. 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
