Each mes- + sage is piped through the <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon, and is placed into the + <a href="QSHAPE_README.html#incoming_queue"><b>incoming</b> queue</a> as one single queue file. The program expects to be run + from the <a href="master.8.html"><b>master</b>(8)</a> process manager. + + The QMQP server implements one access policy: only explicitly autho- + rized client hosts are allowed to use the service. + +<b>SECURITY</b> + The QMQP server is moderately security-sensitive. It talks to QMQP + clients and to DNS servers on the network. The QMQP server can be run + chrooted at fixed low privilege. + +<b>DIAGNOSTICS</b> + Problems and transactions are logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>. + +<b>BUGS</b> + The QMQP protocol provides only one server reply per message delivery. + It is therefore not possible to reject individual recipients. + + The QMQP protocol requires the server to receive the entire message + before replying. If a message is malformed, or if any netstring compo- + nent is longer than acceptable, Postfix replies immediately and closes + the connection. It is left up to the client to handle the situation. + +<b>CONFIGURATION PARAMETERS</b> + Changes to <a href="postconf.5.html"><b>main.cf</b></a> are picked up automatically, as <a href="qmqpd.8.html"><b>qmqpd</b>(8)</a> processes + run for only a limited amount of time.
