I am trying to configure DKIM in SMG 10.9 but the emails are not being sent signed. The steps of the following link were followed
Enabling DKIM signing for a domain
Checking the Header in MXToolbox, the following error appears:
The key is already registered in the DNS domain, checking it shows that it is fine.
I would like to know if there are any extra considerations to take into account or if there is someone who has it working correctly who can help me understand what is missing.
