Postmaster Mail
The defaults for delivery status notifications (DSNs) for postmaster are copywarnpost and copysendpost. In large deployments or environments where the postmaster does not want to get DSNs about users' mail, these keywords should be changed. For a complete explanation of the values, see the Sun ONE Messaging Server documentation. The possible keywords are XYZwarnpost and XYZsendpost, where XYZ is either copy, warn, or err.
