NAME
qmqp-source - multi-threaded QMQP test generator SYNOPSIS
qmqp-source [options] [inet:]host[:port] qmqp-source [options] unix:pathname DESCRIPTION
qmqp-source connects to the named host and TCP port (default 628) and sends one or more messages to it, either sequentially or in parallel. The program speaks the QMQP protocol. Connections can be made to UNIX-domain and IPv4 or IPv6 servers. IPv4 and IPv6 are the default. Note: this is an unsupported test program. No attempt is made to maintain compatibility between successive versions. Arguments: -4 Connect to the server with IPv4. This option has no effect when Postfix is built without IPv6 support. -6 Connect to the server with IPv6. This option is not available when Postfix is built without IPv6 support. -c Display a running counter that is incremented each time a delivery completes. -C count When a host sends RESET instead of SYN|ACK, try count times before giving up. The default count is 1. Specify a larger count in order to work around a problem with TCP/IP stacks that send RESET when the listen queue is full. -f from Use the specified sender address (default: <foo@myhostname>). -l length Send length bytes as message payload. The length includes the message headers. -m message_count Send the specified number of messages (default: 1). -M myhostname Use the specified hostname or [address] in the default sender and recipient addresses, instead of the machine hostname. -r recipient_count Send the specified number of recipients per transaction (default: 1). Recipient names are generated by prepending a number to the recipient address. -s session_count Run the specified number of QMQP sessions in parallel (default: 1). -t to Use the specified recipient address (default: <foo@myhostname>). -R interval Wait for a random period of time 0 <= n <= interval between messages. Suspending one thread does not affect other delivery threads. -v Make the program more verbose, for debugging purposes. -w interval Wait a fixed time between messages. Suspending one thread does not affect other delivery threads. SEE ALSO

NAME
qmqpd - Postfix QMQP server SYNOPSIS
qmqpd [generic Postfix daemon options] DESCRIPTION
The Postfix QMQP server receives one message per connection. Each message 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 authorized client hosts are allowed to use the service. SECURITY
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. DIAGNOSTICS
Problems and transactions are logged to syslogd(8). BUGS
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. CONFIGURATION PARAMETERS
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 text below provides only a parameter summary. See postconf(5) for more details including examples. CONTENT INSPECTION CONTROLS
content_filter (empty) After the message is queued, send the entire message to the specified transport:destination. receive_override_options (empty) Enable or disable recipient validation, built-in content filtering, or address mapping. RESOURCE AND RATE CONTROLS
line_length_limit(2048) Upon input, long lines are chopped up into pieces of at most this length; upon delivery, long lines are reconstructed. hopcount_limit(50) The maximal number of Received: message headers that is allowed in the primary message headers. message_size_limit(10240000) The maximal size in bytes of a message, including envelope information. qmqpd_timeout(300s) The time limit for sending or receiving information over the network. TROUBLE SHOOTING CONTROLS
debug_peer_level(2) The increment in verbose logging level when a remote client or server matches a pattern in the debug_peer_list parameter. debug_peer_list (empty) Optional list of remote client or server hostname or network address patterns that cause the verbose logging level to increase by the amount specified in $debug_peer_level. soft_bounce (no) Safety net to keep mail queued that would otherwise be returned to the sender. TARPIT CONTROLS
qmqpd_error_delay(1s) How long the QMQP server will pause before sending a negative reply to the client. MISCELLANEOUS CONTROLS
config_directory (see 'postconf -d' output) The default location of the Postfix main.cf and master.cf configuration files. daemon_timeout(18000s) How much time a Postfix daemon process may take to handle a request before it is terminated by a built-in watchdog timer. ipc_timeout(3600s) The time limit for sending or receiving information over an internal communication channel. max_idle(100s) The maximum amount of time that an idle Postfix daemon process waits for an incoming connection before terminating voluntarily. max_use(100) The maximal number of incoming connections that a Postfix daemon process will service before terminating voluntarily. process_id (read-only) The process ID of a Postfix command or daemon process. process_name (read-only) The process name of a Postfix command or daemon process. qmqpd_authorized_clients (empty) What clients are allowed to connect to the QMQP server port. queue_directory (see 'postconf -d' output) The location of the Postfix top-level queue directory. syslog_facility (mail) The syslog facility of Postfix logging. syslog_name (see 'postconf -d' output) The mail system name that is prepended to the process name in syslog records, so that "smtpd" becomes, for example, "postfix/smtpd". verp_delimiter_filter (-=+) The characters Postfix accepts as VERP delimiter characters on the Postfix sendmail(1) command line and in SMTP commands. Available in Postfix version 2.5 and later: qmqpd_client_port_logging (no) Enable logging of the remote QMQP client port in addition to the hostname and IP address. SEE ALSO
