There are some known providers that have different formatting requirements to the DKIM format that our portal provides:

Rackspace

Reg-123

DYN

Suggested formatting to try:

Some DNS providers do not allow for double quotes and/or spaces in the Record Text so you will need to manually remove the 4x"

And if removing the Quotation marks doesn't work then please also remove any spaces or line breaks before trying again.

If you still have trouble verifying the DKIM record please don't hesitate to contact support
