Enabling a DKIM signing rule

DKIM signing rules are initially set to OFF. In order to enable a DKIM signing rule, the signing domain must have passed a CNAME record check.

Enable a DKIM signing rule on the Email > Policies > [policy name] > Antispoofing tab, under DKIM Signing. To enable a rule:

• If the CNAME record check has passed, toggle the State switch on ON, then click Save.
• If the CNAME record check has failed, ensure that the CNAME record has been published for the signing domain. For further information on publishing the CNAME record, see DNS records and service IP addresses.

  Once you have published the CNAME record, click Recheck to perform the check again.

To disable a rule, toggle the State switch to OFF, then click Save.
