Message contains invalid header

[User Siggi]

I'm having the following problem.  If someone could tell me why this 
error occurs I would be most thankful.  Platform is Mac OSX Server 10.4.1.

relay=cyrus, delay=1, status=bounced (data format error. Command output: 
john: Message contains invalid header )

This being the message's header.  I changed some of the addresses:

Received: from sendmail.company.com (sendmail.company.com [130.208.xxx.xxx])
        by mx1.company2.com (Postfix) with ESMTP id B75CB19B52F
        for <john at company2.com>; Thu,  9 Jun 2005 14:19:13 +0000 (GMT)
