rejecting mail sent to a deleted users box. 2

[Guest_imported]

Wondering if Exchange 5.5 SP3 will allow you to send a rejection notice to the originator of an email sent to a users box that has been deleted? I do not want the notification that is delivered to the administrators box, I want the sender of the mail notified to stop sending it. Any help will be appriciated.

As we've all see with departed employees and their deleted mailbox, the spam or auto-mail messages just keep coming long after they are gone sometimes its near impossible to get rid of. I took the idea of another Exchange Admin I read from once and:<br><br>1. Created a mailbox called 'deadmail'<br>2. In the configuration for that mailbox go to the E-Mail tab and simply add the 'Internet/SMTP' address of the deleted mailbox receiving mail and in our case we now have 15 to 20 old mailbox addressed in there<br>3. Once in a while go logon to that mailbox and delete the accumlating messages<br><br>Works wonders and you'll not get inbound notification errors again for those userids<br><br>David

Here's another option to avoid having to manually delete the email from all those users.

1. Create a distribution list &quot;deadmail&quot;
2. Go to the email tab and add the dead user's email addresses here.
3. Don't put anyone in the distribution list!

Mail will come to the addresses listed in the email tab and then exchange will distribute to everyone in the deadmail distribution list......which is nobody so it magically disappears.

Good move for old employees, but what about the spammers who are sending to

<randomname>@yourdomain.com

That ALWAYS generates NDR, and so they know what server you have etc.

Ideally it *should* report a 5xx error such as:
557 unknown user - rejected.

and close the connection at the SMTP level, thus avoiding the NDR problem.

Any suggestions??

Well ideally you wouldn't have any NDR messages going back, and would turn them off. This way spammers will not be able to tell legitimate addresses from illegitimate, or tell whether you were there or not.

With regards to ex-employees here: We add a custom recipient called &quot;no-mail&quot; and add any email addresses we do not want to receive mail from to it. No cleaning out, minimal effort - you can hide it from the Global Address List too.
