   9 <b>NAME</b>
  10        cleanup - canonicalize and enqueue Postfix message
  11
  12 <b>SYNOPSIS</b>
  13        <b>cleanup</b> [generic Postfix daemon options]
  14
  15 <b>DESCRIPTION</b>
  16        The  <a href="cleanup.8.html"><b>cleanup</b>(8)</a>  daemon processes inbound mail, inserts it
  17        into the <b>incoming</b> mail queue, and informs the  queue  man-
  18        ager of its arrival.
  19
  20        The <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon always performs the following trans-
  21        formations:
  22
  23        <b>o</b>      Insert missing message  headers:  (<b>Resent-</b>)  <b>From:</b>,
  24               <b>To:</b>, <b>Message-Id:</b>, and <b>Date:</b>.
  25
  26        <b>o</b>      Transform  envelope  and  header  addresses  to the
  27               standard <i>user@fully-qualified-domain</i> form  that  is
  28               expected  by  other Postfix programs.  This task is
  29               delegated to the <a href="trivial-rewrite.8.html"><b>trivial-rewrite</b>(8)</a> daemon.
  30
  31        <b>o</b>      Eliminate duplicate envelope recipient addresses.
  32
  33        The following address transformations are optional:
  34
  35        <b>o</b>      Optionally,  rewrite  all   envelope   and   header
  36               addresses  according  to  the mappings specified in
  37               the <a href="canonical.5.html"><b>canonical</b>(5)</a> lookup tables.
  38
  39        <b>o</b>      Optionally, masquerade  envelope  sender  addresses
  40               and  message  header  addresses (i.e. strip host or
  41               domain information below all domains listed in  the
  42               <b><a href="postconf.5.html#masquerade_domains">masquerade_domains</a></b> parameter, except for user names
  43               listed  in  <b><a href="postconf.5.html#masquerade_exceptions">masquerade_exceptions</a></b>).   By   default,
  44               address   masquerading  does  not  affect  envelope
  45               recipients.
  46
  47        <b>o</b>      Optionally, expand envelope recipients according to
  48               information  found in the <a href="virtual.5.html"><b>virtual</b>(5)</a> lookup tables.
  49
  50        The <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon performs sanity checks on  the  con-
  51        tent  of each message. When it finds a problem, by default
  52        it returns a diagnostic status to the client,  and  leaves
  53        it  up  to  the  client to deal with the problem. Alterna-
  54        tively, the client can request the  <a href="cleanup.8.html"><b>cleanup</b>(8)</a>  daemon  to
  55        bounce  the message back to the sender in case of trouble.
