          Check this
          https://github.com/Pro/dkim-exchange/issues/342

          Also can you actually show your error, it is kind of hard to help without seeing what you see?

                  It is correct as below

                  94b97c23-0e41-4dbc-b0ae-e46eb0e8fd7d-image.png

                  So basically the issues is on the DKIM application but your messages are signed properly.

                      @dbeato step 4 is wrong. The DKIM signer needs to be at the BOTTOM of this list, so it runs last. Otherwise, other transport agents may modify the message, which would render the signatures generated by the signer invalid.

                        @teece I haven't seen that happened ever, no other transport rules modified the DKIM at all.
