Hello Guys,

Please tell me I am doing wrong, I created my DKIM keys for my domain and the CNAME and have propagated. My DKIM now appears to be enabled, however, when I send internal emails, DKIM in the headers still appears as none, while when I send to my gmail account it appears to be pass.

Any ideas what I can do to ensure the DKIM = pass for internal emails

    DKIM is not used for internal messages. its only used so external recipients can verify that your domain sent the message.
    internal messages are authenticated. If an internal message was spoofed, then you need to figure out who sent it as an authenticated user.

    DKIM is only applied to messages sent externally. Why would you need to DKIM for internal messages?

    Actually was because of an internal email that came that was a spoof and was not blocked.

    Trying to ensure it is working going forward
