Administrators can configure default behavior if the contacts do not match any rules. When you create a recipient mailbox, the system default rule is copied as the last regular rule into the list of rules for the recipient mailbox.
Procedure
Start Omnichannel Administration Utility.
In the navigation pane, click E-mail.
Click System Rules.
In the System Default Rule section, in the Routepoint field, select the route point name to apply for the rule.
You must select the Email Route Point that you configured using Avaya Control Manager.
To change the automatic response settings, in the Auto-Responses list, select the required response.
An automatic response is a message sent to a customer without an agent’s interaction.
In the Priority list, select the priority for the contact.
In the right pane, select the attributes.
For example, Language.English.
If you cannot close an email, you can route it to the agent attribute set that is configured in the Edit Attributes section.
