How to Add the postmaster Mailbox to the Aliases

1. Become root and edit the /etc/mail/aliases file on each system.

   If your network does not run NIS or NIS+, edit the /etc/mail/aliases file.

2. Change the postmaster alias from root to Postmaster: postmastermailbox@postmasterhost and save the changes.

3. On the postmaster's local system create an entry in the /etc/mail/aliases file that defines the name of the alias (sysadmin, for example) and includes the path to the local mailbox.

4. Type newaliases and press Return.

   Or you could change the Postmaster: entry in the aliases file to a Postmaster: /usr/somewhere/somefile entry.
