block emails to none existent addresses

I have deleted a number of ex-employees from Active Directory and I want to stop the emails which are being sent to their email addresses from external parties and instead of them coming to me (administrator) from the system administrator on the exchange server to bounce them back to the sender with none deliverable error message, on the lines "the email address is not enabled at the recipients end". Below is the error I get from system administrator.

The following recipient(s) could not be reached:

USERNAME@COMPANY DOMAIN on 07/10/2008 10:33
The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address.
<SERVER #5.1.1>

Not only has the account been deleted in AD but also the email account deleted from Exchange.

We are running SBS 2003 server with Excnage 2003 included.

What is it that you want to achieve?

No bounces to the outside and no-one receive it?  Create a distribution group, add the email addresses you want to kill to that group, then don't add any members.

That is a black hole, and works really well.

Thanks for the reply.

What I would ideally like is any emails that are sent to an ex employee or address that is not on our domain to be sent back from where it originated. EG, Fred Bloggs left last week, he has been deleted from AD and email account fredbloggs@company.com deleted. When someone sends an email to this address, instead of the system administrator account forwarding to me I would like the original email bounced back to the sender with something like "this address is not valid".

I hope that is easier to understand.

You are saying to create a distribution group add the email addresses you want to kill to that group (is this the external senders address?), then don't add any members (is this the internal domain members?). Where is this distribution group added?

Thanks for any help

OK, what is happening now is that people outside are getting the bounces, but you are getting a copy of them.

You *could* setup an autoreply for these old email addresses, but a classic bounce like you are seeing is usually much better.

Don't worry about the distribution group for now, it doesn't bounce the mails, it instantly deletes them

That is what I would Ideally like, set an auto reply back to the sender with my own wording. Or is the classic bounce as I currently have the better option?

There is somewhere in Exchange I can set to stop the notifcations I am getting from the system administrator, can you tell me where that is? I have been checking in Exchange System Manager but cannot locate it.

You can setup a custom message, but it is a pain, and is only going to generate a stack of traffic you don't need.  The standard NDR is the best way to go for long gone users.

Stop the notifications like so -> http://support.microsoft.com/kb/295653

Thanks for that. Think I'll keep as the default NDR message, don't want to generate more work for me...or traffic on the exchange/network.

Found the location to stop forwarding.

Cheers for you help.
