This prevents Postfix from appending the + local domain to spam from poorly written remote clients. + + <b>resolve</b> <i>sender address</i> + Resolve the address to a (<i>transport</i>, <i>nexthop</i>, <i>recipient</i>, <i>flags</i>) + quadruple. The meaning of the results is as follows: + + <i>transport</i> + The delivery agent to use. This is the first field of an + entry in the <a href="master.5.html"><b>master.cf</b></a> file. + + <i>nexthop</i> + The host to send to and optional delivery method informa- + tion. + + <i>recipient</i> + The envelope recipient address that is passed on to <i>nex-</i> + <i>thop</i>. + + <i>flags</i> The address class, whether the address requires relaying, + whether the address has problems, and whether the request + failed. + + <b>verify</b> <i>sender address</i> + Resolve the address for address verification purposes. + +<b>SERVER PROCESS MANAGEMENT</b> + The <a href="trivial-rewrite.8.html"><b>trivial-rewrite</b>(8)</a> servers run under control by the Postfix <a href="master.8.html">mas-</a> + <a href="master.8.html">ter(8)</a> server. Each server can handle multiple simultaneous connec- + tions. When all servers are busy while a client connects, the master + creates a new server process, provided that the trivial-rewrite server + process limit is not exceeded. Each trivial-rewrite server terminates + 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> seconds of + idle time. + +<b>STANDARDS</b> + None.

By default, + this daemon does not talk to remote or local users.
