We have created an alias named listname_del per the docs to do a delete of unknown user and host names when a list is mailed. However, we don't see anything in the docs about how to automate use of this alias. What we want to do is have unknown names deleted automatically from the list if the email to the user doesn't go through. How can we forward rejected messages to the delete alias automatically? Suggestions appreciated. Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
