IP Address was found in the CBL.
It was detected at 2005-10-08 06:00 GMT (+/- 30 minutes).
It has been relisted following a previous removal at 2005-10-06 07:46

Looks as if it was removed and then re-added - that means that you are
an open relay (or not secure!)
Get it sorted before you try and connect your server to the internet

We exchange 2003 server on windows 2003, when ever sending e-mails
outside we are receiving these replies.


 The following recipient(s) could not be reached:

            There was a SMTP communication problem with the recipient's
email server.  Please contact your system administrator.

            < #5.5.0 smtp;550 Denied by policy:
Sender is listed on DNS-based RBL.>



Can any one help in this.
