+CLEANUP(8) CLEANUP(8)
+
+<b>NAME</b>
+ cleanup - canonicalize and enqueue Postfix message
+
+<b>SYNOPSIS</b>
+ <b>cleanup</b> [generic Postfix daemon options]
+
+<b>DESCRIPTION</b>
+ The <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon processes inbound mail, inserts it into the
+ <b>incoming</b> mail queue, and informs the queue manager of its arrival.
+
+ The <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon always performs the following transformations:
+
+ <b>o</b> Insert missing message headers: (<b>Resent-</b>) <b>From:</b>, <b>To:</b>, <b>Mes-</b>
+ <b>sage-Id:</b>, and <b>Date:</b>.
+
+ <b>o</b> Transform envelope and header addresses to the standard
+ <i>user@fully-qualified-domain</i> form that is expected by other Post-
+ fix programs. This task is delegated to the <a href="trivial-rewrite.8.html"><b>trivial-rewrite</b>(8)</a>
+ daemon.
+
+ <b>o</b> Eliminate duplicate envelope recipient addresses.
+
+ <b>o</b> Remove message headers: <b>Bcc</b>, <b>Content-Length</b>, <b>Resent-Bcc</b>,
+ <b>Return-Path</b>.
+
+ The following address transformations are optional:
+
+ <b>o</b> Optionally, rewrite all envelope and header addresses according
+ to the mappings specified in the <a href="canonical.5.html"><b>canonical</b>(5)</a> lookup tables.
+
+ <b>o</b> Optionally, masquerade envelope sender addresses and message
+ header addresses (i.e. strip host or domain information below
+ all domains listed in the <b><a href="postconf.5.html#masquerade_domains">masquerade_domains</a></b> parameter, except
+ for user names listed in <b><a href="postconf.5.html#masquerade_exceptions">masquerade_exceptions</a></b>). By default,
+ address masquerading does not affect envelope recipients.
+
+ <b>o</b> Optionally, expand envelope recipients according to information
+ found in the <a href="virtual.5.html"><b>virtual</b>(5)</a> lookup tables.
+
+ The <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon performs sanity checks on the content of each
+ message. When it finds a problem, by default it returns a diagnostic
+ status to the client, and leaves it up to the client to deal with the
+ problem. Alternatively, the client can request the <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon to
+ bounce the message back to the sender in case of trouble.
+
+<b>STANDARDS</b>
+ <a href="http://tools.ietf.org/html/rfc822">RFC 822</a> (ARPA Internet Text Messages)
+ <a href="http://tools.ietf.org/html/rfc2045">RFC 2045</a> (MIME: Format of Internet Message Bodies)
+ <a href="http://tools.ietf.org/html/rfc2046">RFC 2046</a> (MIME: Media Types)
+ <a href="http://tools.ietf.org/html/rfc2822">RFC 2822</a> (Internet Message Format)

+ <a href="http://tools.ietf.org/html/rfc5322">RFC 5322</a> (Internet Message Format)
+
+<b>DIAGNOSTICS</b>
+ Problems and transactions are logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>.
+
+<b>BUGS</b>
+ Table-driven rewriting rules make it hard to express <b>if then else</b> and
+ other logical relationships.
+
+<b>CONFIGURATION PARAMETERS</b>
+ Changes to <a href="postconf.5.html"><b>main.cf</b></a> are picked up automatically, as <a href="cleanup.8.html"><b>cleanup</b>(8)</a> processes
+ run for only a limited amount of time. Use the command "<b>postfix reload</b>"
+ to speed up a change.
