One thing that you need to consider when using Cyrus in this type of environment is that any mail to a user that is not in the Cyrus database will be rejected by Cyrus. This is especially true for the root user. It is not a good idea to store the root user mail in Cyrus, so most people configure an alias for root's mail to be delivered to a non-administrative user. Here we configure root's mail to be delivered to the user justin:
1. Open the file /etc/aliases and add an entry for the root user:
This tells Postfix that any mail for root should actually be delivered to the user justin.
2. When /etc/aliases is edited, run the postalias command:
bible:~ # postalias /etc/aliases
3. You then need to reload Postfix's databases to commit the new alias.
