QMQPD(8)							      QMQPD(8)

       qmqpd - Postfix QMQP server

       qmqpd [generic Postfix daemon options]

       The Postfix QMQP server receives one message per connection.  Each mes‐
       sage is piped through the cleanup(8) daemon, and	 is  placed  into  the
       incoming queue as one single queue file.	 The program expects to be run
       from the master(8) process manager.

       The QMQP server implements one access policy:  only  explicitly	autho‐
       rized client hosts are allowed to use the service.

       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.

       Problems and transactions are logged to syslogd(8).

       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.

       Changes	to  main.cf are picked up automatically, as qmqpd(8) processes
       run for only a limited amount of time. Use the command "postfix reload"
       to speed up a change.

	      The  time	 limit	for  sending or receiving information over the

       debug_peer_level (2)
	      The increment in verbose logging level when a remote  client  or

       debug_peer_list (empty)
	      Optional	list  of  remote  client or server hostname or network

	      Safety  net to keep mail queued that would otherwise be returned
	      to the sender.

       qmqpd_error_delay (1s)

	      request before it is terminated by a built-in watchdog timer.

       ipc_timeout (3600s)
	      The  time	 limit	for  sending  or receiving information over an

	      The syslog facility of Postfix logging.

       syslog_name (see 'postconf -d' output)
	      The mail system name that is prepended to the  process  name  in
