DomainKey signing isn't working.

Applicable to:

  • Plesk 12.5 for Linux
  • Plesk 11.x for Linux
  • Plesk 12.0 for Linux


DomainKey signing isn't working. DKIM support is also installed and configured.


DKIM and DomainKeys interoperability conflict occurred because of both DKIM and DomainKeys were configured to use the same default selector, but crypto keys for these two systems are differ.


Changes should be made on DKIM side.

  1. Change DKIM selector from default to something else, for example, mail in opendkim.conf
  2. Add corresponding TXT record ( mail._domainkey.domain.tld. ) in Plesk for domain.tld from /etc/opendkim/keys/domain.tld/mail.txt .
  3. Wait for 'Propagation period'

Note : DKIM is not supported in Plesk 12.5 and earlier. DKIM support in Plesk announced since Plesk Onyx. Implementation details available here
