Subject: [Mailman-Users] Mailman messages getting rejected by Exchange relays running Webs hield

All,
I have set up mailman running on Slackware 8.0 w/ the latest slackware sendmail patches.  Some of the list subscribers are having mail addressed to the list bounced by Exchange servers running Webshield SMTP V4.5 MR1a Mail Service.

Additionally, when a message is sent from Mailman to a user that has to be relayed through one of these servers, it times out with the log entry "input channel closed by host".  If it relays through a different path, there are no problems.

Sometimes the reject messages is simply "host not found" and sometime it is:

Network Associates WebShield SMTP V4.5 MR1a on arwshkhn42 intercepted a mail from
<[EMAIL PROTECTED]> which caused the Content Filter MyLife.F to be
triggered.

Even sending from a 'nix box will generate the above if it relays through the server in question.

This seems to occur during a reply to a message.

The common denominator is Webshield, all other machines, including Exchange, relay the message just fine.

Is this a problem with Mailman?  Have I configured Sendmail incorrectly?  Or is this just a result of somebody incorrectly installing/configuring Webshield?  Any suggestions would be welcome.
