Probably no solution!!
This is tha same, that someone in the world, sends an e-mail to "h8/66$#nf/&?$"

You can be sure that user/mailbox "h8/66$#nf/&?$" at Microsoft does not exist.

Microsoft will receive the message (since Microsoft does exist), but the Administrators wil receive the same notifications than you.

As far as i know, you can't.

But take care, that it's dessigned to evaluete those messages to study WHY those messagges are rejected.
In your case, YOU KNOW that those mailboxes don't exist.
But in ohter cases, you can trace the problem.

Anyway, you could create a DL, and include those rejected mailbox. Then, create an autoreply for 1 or two months to inform the sender that this addess does not existe anmyore.
(the sender receives the aknlowdge of the server, but in this way you can customize it)

Hope i cleared it.

First of all, create as many mailboxes as recipients you're receiving the undesirable messagees and in the primary NT account, select your user.


Create a DL (Distribution List) (in this case for future deletion of the problematic mailboxes to not read your entire list of recipients)

FIle Menu, Create Distribution List item.
This is the same than creating a single mailbox, but you can add existing users to it (the ones you created before).
When you someone sends a that DL, every mailbox in it will receive the message.

The autoreply has to be configured here.
Log in the network as yourself, configure the outlook with one of the recipients mailboxes and select TOOLS - Out of office Assistant to send autoreplies.

Now, everyone who sends an e-mail to one of those mentioned mailboxes, will get a message that you typed in the before step.

IN THE SERVER IMS Connector / Internet Mail tab / Advanced Options button, the "Disable Out of Office response to the Internet" and "Disable Automatic Replies to the Internet", MUST BE UNCHECKED!!!

Hope it helps.
