    I am having trouble with the DKIM signature body hash not verifying. MX Toolbox is reporting this problem when I ping test send an email to the delivery check tool.

    When I go to the Email Deliverability for the domain, it shows the DKIM record as valid.

    I am on cPanel 78.0.17 and my DNS is hosted on the same server as Exim. Is there a problem with the way Exim is signing? or the way MXToolbox is validating? Or is there somewhere else I should be looking?

    Hello @Volox,

    Can you open a support ticket so we can take a look at the actual record and verify it's setup correctly? You can post the ticket number here and we'll link this thread to it.

    Thank you.

    Most likely related to custom keys for 3dparty DNS services. Have you been creating shortened DKIM keys eg 1024bit?

    To update, it looks like this was a false positive from MXToolBox. It's testing utility requires that DMARC is enabled for a domain in order for it to pass DKIM verification.

    Thank you.
