<b>trivial-rewrite</b> [generic Postfix daemon options]
17
The <b>trivial-rewrite</b> daemon processes three types of client
21
Rewrite an address to standard form. The <b>trivial-</b>
22
<b>rewrite</b> daemon by default appends local domain
23
information to unqualified addresses, swaps bang
24
paths to domain form, and strips source routing
25
information. This process is under control of sev-
26
eral configuration parameters (see below).

The <a href="trivial-rewrite.8.html"><b>trivial-rewrite</b>(8)</a> daemon processes three types of
18
client service requests:
20
<b>rewrite</b> <i>context address</i>
21
Rewrite an address to standard form, according to
22
the address rewriting context:
24
<b>local</b> Append the domain names specified with <b>$<a href="postconf.5.html#myorigin">myo</a>-</b>
25
<b><a href="postconf.5.html#myorigin">rigin</a></b> or <b>$<a href="postconf.5.html#mydomain">mydomain</a></b> to incomplete addresses;
26
do <b><a href="postconf.5.html#swap_bangpath">swap_bangpath</a></b> and <b><a href="postconf.5.html#allow_percent_hack">allow_percent_hack</a></b> pro-
27
cessing as described below, and strip source
28
routed addresses (<i>@site,@site:user@domain</i>)
29
to <i>user@domain</i> form.
31
<b>remote</b> Append the domain name specified with
32
<b>$<a href="postconf.5.html#remote_header_rewrite_domain">remote_header_rewrite_domain</a></b> to incomplete
33
addresses. Otherwise the result is identical
34
to that of the <b>local</b> address rewriting con-
35
text. This prevents Postfix from appending
36
the <a href="ADDRESS_CLASS_README.html#local_domain_class">local domain</a> to spam from poorly written

<b>SERVER PROCESS MANAGEMENT</b>
49
The trivial-rewrite servers run under control by the Post-
50
fix master server. Each server can handle multiple simul-
51
taneous connections. When all servers are busy while a
52
client connects, the master creates a new server process,
53
provided that the trivial-rewrite server process limit is
54
not exceeded. Each trivial-rewrite server terminates
55
after serving at least <b>$<a href="postconf.5.html#max_use">max_use</a></b> clients of after <b>$<a href="postconf.5.html#max_idle">max_idle</a></b>
