Multiple copies of same mail in ~/public-directory

["Stefan Kaminski" <kaminski@scm.de>]

Dear collegues,

I am working with Zmailer-Version (2.99.49p3) under Linux 2.0.0. 
Everything is working quite smooth, except the following.

While the system is running an increasing amount of files with the 
same content is created in the "~/public"-directory. Almost all of 
these mails are sent by mailing lists to recipients on our mail 
server. The header of these mails read as follows.

   Received: from mail.postbox.co.uk ([194.205.1.110] HELO 
                   postbox.co.uk ident: NO-IDENT-SERVICE [port 
                   28433]) by mailer.scm.de with SMTP id 
                   <55639-29685>; Fri, 29 Aug 1997 17:53:37 +0200 
   Received: from [194.154.62.72] by postbox.co.uk (NTList 3.02.12) 
                    id ta124325; Thu, 28 Aug 1997 23:09:10 +0100 
   Received: from nobody by stingray.ivision.co.uk with local (Exim

   Message-Id: <E0x4CWy-0001oM-00@stingray.ivision.co.uk>
   Sender: Nobody <nobody@ivision.co.uk>
   Precedence: bulk
   X-ListMember: kaminski@mailer.scm.de 
                             [economist-business@postbox.co.uk] 
   Return-Path: <economist-business-return@postbox.co.uk>
    X-UIDL: 370df23de8216a86ba325d802d089f56

There are two entries in the header that arose my suspiscion. These 
are the entries "NO-IDENT-SERVICE" and the "Precedence: bulk". 

Although, I have temporarily removed the smtp-policy entries, the 
problem still consists. It seems to me as if the mailing-list-owner 
does not receive a "delivered"-information. So the mailing-list- 
program starts over and over again and tries to deliver the message. 
And this leads to the submission of always the same mail to the 
recipient.

The worst case we experienced so far was that the hard disk was full 
of messages with the same content. As a work-around, I have now
temporarily inserted a cron-job which moves all the files from the 
public-directory to the router-directory every five minutes. But 
this is not the way I'd like to have solved that problem,  because 
now the recipients receive plenty of mail messages with the same 
content.

Is there an option I forgot to set, or has anybody experienced the 
same problem ? Any ideas ? I appreciate every comment on that.
