<b>NAME</b>
|
|
trivial-rewrite - Postfix address rewriting and resolving
|
|
daemon
|
|
|
|
<b>SYNOPSIS</b>
|
|
<b>trivial-rewrite</b> [generic Postfix daemon options]
|
|
|
|
<b>DESCRIPTION</b>
|
|
The <b>trivial-rewrite</b> daemon processes two types of client
|
|
service requests:
|
|
|
|
<b>rewrite</b>
|
|
Rewrite an address to standard form. The <b>trivial-</b>
|
|
<b>rewrite</b> daemon by default appends local domain
|
|
information to unqualified addresses, swaps bang
|
|
paths to domain form, and strips source routing
|
|
information. This process is under control of sev-
|
|
eral configuration parameters (see below).
|
|
|
|
<b>resolve</b>
|
|
Resolve an address to a (<i>transport</i>, <i>nexthop</i>, <i>recip-</i>
|
|
<i>ient</i>) triple. The meaning of the results is as fol-
|
|
lows:
|
|
|
|
<i>transport</i>
|
|
The delivery agent to use. This is the first
|
|
field of an entry in the <b>master.cf</b> file.
|
|
|
|
<i>nexthop</i>
|
|
The host to send to. For local delivery this
|
|
is an empty string.
|
|
|
|
<i>recipient</i>
|
|
The envelope recipient address that is
|
|
passed on to <i>nexthop</i>.
|
|
|
|
The <b>trivial-rewrite</b> daemon by default only distin-
|
|
guishes between local and non-local mail. For finer
|
|
control over mail routing, use the optional <a href="transport.5.html"><b>trans-</b></a>
|
|
<a href="transport.5.html"><b>port</b>(5)</a> lookup table.
|
|
|
|
This program expects to be run from the <a href="master.8.html"><b>master</b>(8)</a> process
|
|
manager.
|
|
|
|
<b>STANDARDS</b>
|
|
None. The command does not interact with the outside
|
|
world.
|
|
|
|
<b>SECURITY</b>
|
|
The <b>trivial-rewrite</b> daemon is not security sensitive. By
|
|
default, this daemon does not talk to remote or local
|
|
users. It can run at a fixed low privilege in a chrooted
|
|
environment.

<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>Miscellaneous</b>
|
|
<b>inet</b><i>_</i><b>interfaces</b>
|
|
The network interfaces that this mail system
|
|
receives mail on. This information is used to
|
|
determine if <i>user</i>@[<i>net.work.addr.ess</i>] is local or
|
|
remote.
|
|
|
|
<b>mydestination</b>
|
|
List of domains that this machine considers local.
|
|
|
|
<b>myorigin</b>
|
|
The domain that locally-posted mail appears to come
|
|
from.
|
|
|
|
<b>Rewriting</b>
|
|
<b>allow</b><i>_</i><b>percent</b><i>_</i><b>hack</b>
|
|
Rewrite <i>user</i>%<i>domain</i> to <i>user</i>@<i>domain</i>.
|
|
|
|
<b>append</b><i>_</i><b>at</b><i>_</i><b>myorigin</b>
|
|
Rewrite <i>user</i> to <i>user</i>@$<b>myorigin</b>.
|
|
|
|
<b>append</b><i>_</i><b>dot</b><i>_</i><b>mydomain</b>
|
|
Rewrite <i>user</i>@<i>host</i> to <i>user</i>@<i>host</i>.$<b>mydomain</b>.
|
|
|
|
<b>swap</b><i>_</i><b>bangpath</b>
|
|
Rewrite <i>site</i>!<i>user</i> to <i>user</i>@<i>site</i>.
|
|
|
|
<b>Routing</b>
|
|
<b>local</b><i>_</i><b>transport</b>
|
|
Where to deliver mail for destinations that match
|
|
$<b>mydestination</b> or $<b>inet</b><i>_</i><b>interfaces</b>. The default
|
|
transport is <b>local</b>.
|
|
|
|
Syntax is <i>transport</i>:<i>nexthop</i>; see <a href="transport.5.html"><b>transport</b>(5)</a> for
|
|
details. The :<i>nexthop</i> part is optional.
|
|
|
|
<b>default</b><i>_</i><b>transport</b>
|
|
Where to deliver non-local mail when no information
|
|
is explicitly given in the <a href="transport.5.html"><b>transport</b>(5)</a> table. The
|
|
default transport is <b>smtp</b>.
|
|
|
|
Syntax is <i>transport</i>:<i>nexthop</i>; see <a href="transport.5.html"><b>transport</b>(5)</a> for
|
|
details. The :<i>nexthop</i> part is optional.

|
<b>relayhost</b>
|
|
The default host to send non-local mail to when no
|
|
entry is matched in the <a href="transport.5.html"><b>transport</b>(5)</a> table.
|
|
|
|
When no <b>relayhost</b> is specified, mail is routed
|
|
directly to the destination's mail exchanger.
|
|
|
|
<b>transport</b><i>_</i><b>maps</b>
|
|
List of tables with <i>domain</i> to (<i>transport,</i> <i>nexthop</i>)
|
|
mappings.
