  28 Enough daemon talk. The anatomy lesson ends with an introduction
  29 to command-line utilities for day-to-day use of the Postfix mail
  30 system. Besides the <a href="sendmail.1.html">sendmail</a>, <a
  31 href="sendmail.1.html">mailq</a>, and <a
  32 href="sendmail.1.html">newaliases</a> commands that were already
  33 introduced, the Postfix system comes with it own collection of
  34 utilities. For consistency, these are all named post<i>something</i>.
  35
  36 <ul>
  37
  38 <li>The <a href="postfix.1.html">postfix</a> command controls the
  39 operation of the mail system. It is the interface for starting and
  40 stopping the mail system, and for some other administrative
  41 operations.  This command is reserved to the super-user.
  42
  43 <p>
  44
  45 <li>The <a href="postalias.1.html">postalias</a> command maintains
  46 Postfix <a href="aliases.5.html">alias</a> databases. This is the
  47 program behind the <a href="newaliases.1.html">newaliases</a>
  48 command.
  49
  50 <p>
  51
  52 <li>The <a href="postcat.1.html">postcat</a> command displays the
  53 contents of Postfix queue files. This is a limited, preliminary
  54 utility.  This program is likely to be superseded by something more
  55 powerful that can also edit Postfix queue files.
  56
  57 <p>
  58
  59 <li>The <a href="postconf.1.html">postconf</a> command displays
  60 Postfix <b>main.cf</b> parameters: actual values, default values,
  61 or parameters that have non-default settings.  This is a limited,
  62 preliminary utility.  This program is likely to be superseded by
  63 something more powerful that can not only list but also edit the
  64 <b>main.cf</b> file.
  65
  66 <p>
  67
  68 <li>The <a href="postdrop.1.html">postdrop</a> command is the mail
  69 posting utility that is run by the <a href="sendmail.1.html">sendmail</a>
  70 command in order to deposit mail into the <b>maildrop</b> queue
  71 directory.
  72
  73 <p>
  74
  75 <li>The <a href="postkick.1.html">postkick</a> command makes some
  76 internal communication channels available for use in, for example,
  77 shell scripts.
  78
  79 <p>
  80
  81 <li>The <a href="postlock.1.html">postlock</a> command provides
  82 Postfix-compatible mailbox locking for use in, for example, shell
  83 scripts.
  84
  85 <p>
  86
  87 <li>The <a href="postlog.1.html">postlog</a> command provides
  88 Postfix-compatible logging for shell scripts.
  89
  90 <p>
  91
  92 <li>The <a href="postmap.1.html">postmap</a> command maintains
  93 Postfix lookup tables such as <a href="canonical.5.html">canonical</a>,
  94 <a href="virtual.5.html">virtual</a> and others. It is a cousin of
  95 the UNIX <b>makemap</b> command.
  96
  97 <p>
  98
  99 <li>The <a href="postqueue.1.html">postqueue</a> command is the
 100 utility that is run by the <a href="sendmail.1.html">sendmail</a>
 101 command in order to flush or list the mail queue.
 102
 103 <p>
 104
 105 <li>The <a href="postsuper.1.html">postsuper</a> command maintains
 106 the Postfix queue. It removes old temporary files, and moves queue
 107 files into the right directory after a change in the hashing depth
 108 of queue directories. This command is run at mail system startup time.
