104 Chapter 11 Working With Mail Service
Changing Mail Service Settings
You can use serveradmin to modify your server’s mail configuration. However, if you
want to work with the Mail service from the command-line, you’ll probably find it more
straightforward to work directly with the underlying Postfix and Cyrus mail services.
For information on Postfix, visit www.postfix.org.
For information on Cyrus IMAP/POP, visit asg.web.cmu.edu/cyrus.
You can also use Sherlock or Google to search the web for information on Postfix or
Cyrus.

Use the following parameters with the serveradmin command to change settings for
