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. 56 57<b>STANDARDS</b> 58 <a href="http://tools.ietf.org/html/rfc822">RFC 822</a> (ARPA Internet Text Messages) 59 <a href="http://tools.ietf.org/html/rfc2045">RFC 2045</a> (MIME: Format of Internet Message Bodies) 60 <a href="http://tools.ietf.org/html/rfc2046">RFC 2046</a> (MIME: Media Types) 61 <a href="http://tools.ietf.org/html/rfc2822">RFC 2822</a> (Internet Message Format) 62 <a href="http://tools.ietf.org/html/rfc3463">RFC 3463</a> (Enhanced Status Codes) 63 <a href="http://tools.ietf.org/html/rfc3464">RFC 3464</a> (Delivery status notifications) 64 <a href="http://tools.ietf.org/html/rfc5322">RFC 5322</a> (Internet Message Format) 65 66<b>DIAGNOSTICS</b> 67 Problems and transactions are logged to <b>syslogd</b>(8). 68 69<b>BUGS</b> 70 Table-driven rewriting rules make it hard to express <b>if</b> 71 <b>then else</b> and other logical relationships. 72 73<b>CONFIGURATION PARAMETERS</b> 74 Changes to <a href="postconf.5.html"><b>main.cf</b></a> are picked up automatically, as 75 <a href="cleanup.8.html"><b>cleanup</b>(8)</a> processes run for only a limited amount of 76 time.
