Log into Plesk.
Go to Tools & Settings > Mail Server Settings > DKIM spam protection section.
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.
