      It seems the first delivery fails (after 10 minutes), and the
      subsequent retry succeeds immediately. It strikes me as odd that the
      mail is being retried in the very second the error message ist being
      logged.

        The message was immediately accepted by the second MX host for
        vivantes.de after the first MX host timed out.

          ARGH. Thanks for the second set of eyes.
          I just didn't see mail|mail1 (was expecting mail|mail2 or something
          along those lines).

            Delivery fails to the primary MX host (mail.vivantes.de) and then
            it succeeds to the secondary MX host. Why should Postfix wait when
            it switches from primary to secondary MX?
