Email Black Hole
If you have an email address that is getting nothing but spam and you want to drop all of the email that it receives without even viewing it, then you need to send it in to a black hole.
This uses a feature of Exchange where any email that is sent to a distribution list is no longer stored on the server once it has been delivered to the list, even if the list has no members.
This is very simple to setup
- Create a mail enabled distribution list called "black hole" but don't add any members to it.
- Add the email addresses that you want to "black hole" to the email address tab.
Any email sent to that address will simply disappear - never to be seen again.
This can also be used if you need to send an email out but don't want to see any replies - the no-reply type email address.
Exchange 2003/2007 - Filter Unknown Users
If you are using Exchange 2003 or higher then you may prefer to use a built in feature to filter out unknown users. For this feature to work the email address must not exist within the Exchange environment, but can be more effective as the email is never even delivered to the server. More information on using this feature can be found here for Exchange 2003 and here for Exchange 2007.
