    QMQP-SINK(1)                                                      QMQP-SINK(1)

    NAME
           qmqp-sink - multi-threaded QMQP test server

    SYNOPSIS
           qmqp-sink [-46cv] [-x time] [inet:][host]:port backlog

           qmqp-sink [-46cv] [-x time] unix:pathname backlog

    DESCRIPTION
           qmqp-sink listens on the named host (or address) and port.  It receives
           messages from the network and throws them away.  The purpose is to mea-
           sure QMQP client performance, not protocol compliance.  Connections can
           be accepted on IPv4 or IPv6 endpoints, or on UNIX-domain sockets.  IPv4
           and  IPv6 are the default.  This program is the complement of the qmqp-
           source(1) program.

           Note: this is an unsupported test program. No attempt is made to  main-
           tain compatibility between successive versions.

           Arguments:

           -4     Support  IPv4  only.  This  option has no effect when Postfix is
                  built without IPv6 support.

           -6     Support IPv6 only. This option is not available when Postfix  is
                  built without IPv6 support.

           -c     Display a running counter that is updated whenever a delivery is
                  completed.

           -v     Increase verbosity. Specify -v -v to see some of the  QMQP  con-
                  versation.

           -x time
                  Terminate  after time seconds. This is to facilitate memory leak
                  testing.
