Does anyone else get these blank failed deliveries?

[Chris Green]

Every time I send a message to the Cygwin/X list I get an empty bounce
with the following headers:-

    From devnull@ise.de  Fri Dec 17 15:53:40 2004
    From: Mail Delivery Subsystem <MAILER-DAEMON@ise.de>
    Subject: Returned mail: User unknown
    To: chris.green@isbd.co.uk
    Date: Fri, 17 Dec 2004 15:48:04 +0000 (GMT)
 
Is anyone else experiencing this?
