    Thanks for the hint.

    This is a custom spam filter script. Before the mail is re-submitted by
    this user it is first accepted by postfix.

    And still the question arises why postfix accepts the mail initially:

    Received: from EXCHANGE (brmn-4db7427e.pool.einsundeins.de [77.183.66.126])
             by mail.dextermedia.net (Postfix) with ESMTP id 8A8D38062DD
             for <>; Sat, 29 Sep 2007 14:37:37 +0200
    (CEST)

    This should not be. If I try to submit a mail for
     via telnet it is rejected, so I can't figure
    where the difference is.

    Best regards

    Eddy
