Can an 'override address' be configured with UTL_SMTP?

Hi,

My database is 11.2.0.2

In Oracle E-Business suite we can set an 'override address' for the Workflow Notification Mailer, e.g. in a test environment all emails will be routed to the override email address rather than being sent to Live Accounts.  Is there similar functionality for the UTL_SMTP package?  We would like to use this package but need to test it first; rather than updating the 'email column' with the test address we would like to understand if UTL_SMTP can be configured to simply send to a predefined 'override address' even if accidentally passed a Live Email Account.
