You can use the Default User Mail Account option in the Oracle Alert Options window to set the Operating System Login ID or Application Username. If the Send an electronic mail notification alert action is invoked during quality data collection, but one of the recipient IDs (To, CC, or Bcc) is invalid, the system attempts to return the message to the user who invoked the alert using the email or fax ID that was set up for that user in the Users window (from the System Administrators responsibility). If the value of the email or fax field for the user is null, then the system returns the message to either the Operating System Login ID or Application Username.
You can also use Oracle Alert to define distribution lists. You must define distribution lists before using them to define the recipients (To, CC, and Bcc) of an electronic mail notification alert. Refer the Overview of Setting Up section in the Oracle Alert User's Guide.
