<strong>Postfix</strong> Anatomy - Command-line Utilities<br />
Up one level | Receiving Mail | Delivering Mail | Behind the Scenes | Command-line Utilities<br />
Enough daemon talk. The anatomy lesson ends with an introduction to command-line utilities for day-to-day<br />
use of the <strong>Postfix</strong> mail system. Besides the sendmail, mailq, and newaliases commands that were already<br />
introduced, the <strong>Postfix</strong> system comes with it own collection of utilities. For consistency, these are all named<br />
postsomething.<br />
• The postfix command controls the operation of the mail system. It is the interface for starting and<br />
stopping the mail system, and for some other administrative operations. This command is reserved to the<br />
super-user.<br />
• The postalias command maintains <strong>Postfix</strong> alias databases. This is the program behind the newaliases<br />
command.<br />
• The postcat command displays the contents of <strong>Postfix</strong> queue files. This is a limited, preliminary utility.<br />
This program is likely to be superseded by something more powerful that can also edit <strong>Postfix</strong> queue<br />
files.<br />
• The postconf command displays <strong>Postfix</strong> main.cf parameters: actual values, default values, or parameters<br />
that have non-default settings. This is a limited, preliminary utility. This program is likely to be<br />
superseded by something more powerful that can not only list but also edit the main.cf file.<br />
• The postdrop command is the mail posting agent that is run by the sendmail command on systems that<br />
have no world-writable maildrop queue directory.<br />
• The postkick command makes some internal communication channels available for use in, for example,<br />
shell scripts.<br />
• The postlock command provides <strong>Postfix</strong>-compatible mailbox locking for use in, for example, shell<br />
scripts.<br />
• The postlog command provides <strong>Postfix</strong>-compatible logging for shell scripts.<br />
• The postmap command maintains <strong>Postfix</strong> lookup tables such as canonical, virtual and others. It is a<br />
cousin of the UNIX makemap command.<br />
• The postsuper command maintains the <strong>Postfix</strong> queue. It removes old temporary files, and moves queue<br />
files into the right directory after a change in the hashing depth of queue directories. This command is run<br />
at mail system startup time.<br />
