Blocking email sent to some email addresses

Hi,

We have a lot of emails being sent to email address of users who have already left our company or to wrong email addresses.  These email are being sent from mailing lists or group that the users had subscribed to while they were working for our company.

I want to be able to block all mails being SENT to these addresses.  Can anyone help me achieve this.

Thank you.
Ismail

create a new group in Server address book.
In the configuration document, in the Router ->Inbound Tab, Deny Messagesfrom the folow...filed, place this Group name.

Although the technique is correct, Maddy gives you the incorrect section.

It's in "Deny messages intended for the following internet addresses:  ", inbound intended recipients.

The group should contain the emailaddresses in format name@domain.tld , not the Notes name !

cheers,

Tom

My mail server sends back an email to the sender notifying them that the email address they are trying to reach is not available in the Public address book.  

Most of the emails that these email addresses are getting are from mailing lists and therefore my email server has to do double the work :- firstly it has to process an email to the unavailable address, secondly it has to notify the other party (which does not accept reply's) that this email address does not exist.

Can I prevent my server from sending a reply back only for these email addreses?  Is there a way by which the server directly deletes the emails that are addressed to the email I specify ?

Thank you

The machnism Tom described is designed to do what you want.  The SMTP internet mail server will simplyrefuse to accept the messages as it comes in.  The server sending the message way try to give a non-delivery report back to teh sender, but that IS NORMAL INTERNET OPERATION, and is perfectly fine.  You won't get a "bounce" message back, because all group mailers are designed to assume that some addresses will no longer exist and will cause bouncebacks.
