<b>NAME</b>
|
|
cleanup - canonicalize and enqueue Postfix message
|
|
|
|
<b>SYNOPSIS</b>
|
|
<b>cleanup</b> [generic Postfix daemon options]
|
|
|
|
<b>DESCRIPTION</b>
|
|
The <b>cleanup</b> daemon processes inbound mail, inserts it into
|
|
the <b>incoming</b> mail queue, and informs the queue manager of
|
|
its arrival.
|
|
|
|
The <b>cleanup</b> daemon always performs the following transfor-
|
|
mations:
|
|
|
|
<b>o</b> Insert missing message headers: (<b>Resent-</b>) <b>From:</b>,
|
|
<b>To:</b>, <b>Message-Id:</b>, and <b>Date:</b>.
|
|
|
|
<b>o</b> Extract envelope recipient addresses from (<b>Resent-</b>)
|
|
<b>To:</b>, <b>Cc:</b> and <b>Bcc:</b> message headers when no recipi-
|
|
ents are specified in the message envelope.
|
|
|
|
<b>o</b> Transform envelope and header addresses to the
|
|
standard <i>user@fully-qualified-domain</i> form that is
|
|
expected by other Postfix 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.
|
|
|
|
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>masquerade</b><i>_</i><b>domains</b> parameter, except for user names
|
|
listed in <b>masquerade</b><i>_</i><b>exceptions</b>). Address mas-
|
|
querading 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 <b>cleanup</b> 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 <b>cleanup</b> daemon to bounce the
|
|
message back to the sender in case of trouble.

<b>DIAGNOSTICS</b>
|
|
Problems and transactions are logged to <b>syslogd</b>(8).
|
|
|
|
<b>BUGS</b>
|
|
Table-driven rewriting rules make it hard to express <b>if</b>
|
|
<b>then</b> <b>else</b> and other logical relationships.
|
|
|
|
<b>CONFIGURATION</b> <b>PARAMETERS</b>
|
|
The following <b>main.cf</b> parameters are especially relevant
|
|
to this program. See the Postfix <b>main.cf</b> file for syntax
|
|
details and for default values. Use the <b>postfix</b> <b>reload</b>
|
|
command after a configuration change.
|
|
|
|
<b>Content</b> <b>filtering</b>
|
|
<b>body</b><i>_</i><b>checks</b>
|
|
Lookup tables with content filters for message body
|
|
lines. These filters see physical lines one at a
|
|
time, in chunks of at most line_length_limit bytes.
|
|
|
|
<b>header</b><i>_</i><b>checks</b>
|
|
Lookup tables with content filters for message
|
|
header lines. These filters see logical headers
|
|
one at a time, including headers that span multiple
|
|
lines.
|
|
|
|
<b>Miscellaneous</b>
|
|
<b>always</b><i>_</i><b>bcc</b>
|
|
Address to send a copy of each message that enters
|
|
the system.
|
|
|
|
<b>hopcount</b><i>_</i><b>limit</b>
|
|
Limit the number of <b>Received:</b> message headers.
|
|
|
|
<b>undisclosed</b><i>_</i><b>recipients</b><i>_</i><b>header</b>
|
|
The header line that is inserted when no recipients
|
|
were specified in (Resent-)To: or (Resent-)Cc: mes-
|
|
sage headers.
|
|
|
|
<b>Address</b> <b>transformations</b>
|
|
<b>empty</b><i>_</i><b>address</b><i>_</i><b>recipient</b>
|
|
The destination for undeliverable mail from <>.
|
|
This substitution is done before all other address
|
|
rewriting.

|
|
<b>canonical</b><i>_</i><b>maps</b>
|
|
Address mapping lookup table for sender and recipi-
|
|
ent addresses in envelopes and headers.

<b>recipient</b><i>_</i><b>canonical</b><i>_</i><b>maps</b>
|
|
Address mapping lookup table for envelope and

|
header recipient addresses.
