QMQP-SOURCE(1) General Commands Manual QMQP-SOURCE(1) 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

QMQPD(8) System Manager's Manual QMQPD(8) 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
The following main.cf parameters are especially relevant to this program. See the Postfix main.cf file for syntax details and for default values. Use the postfix reload command after a configuration change. Miscellaneous always_bcc Address to send a copy of each message that enters the system. debug_peer_level Increment in verbose logging level when a remote host matches a pattern in the debug_peer_list parameter. debug_peer_list List of domain or network patterns. When a remote host matches a pattern, increase the verbose logging level by the amount specified in the debug_peer_level parameter. hopcount_limit Limit the number of Received: message headers. qmqpd_authorized_clients A list of domain or network patterns that specifies what clients are allowed to use the service. qmqpd_timeout Limit the time to send a server response and to receive a client request. soft_bounce Change hard (D) reject responses into soft (Z) reject responses. This can be useful for testing purposes. Content inspection controls content_filter The name of a mail delivery transport that filters mail and that either bounces mail or re-injects the result back into Postfix. This parameter uses the same syntax as the right-hand side of a Postfix transport table. Resource controls line_length_limit Limit the amount of memory in bytes used for the handling of partial input lines, and the length of sender and recipient addresses that are received from client. message_size_limit Limit the total size in bytes of a message, including on-disk storage for sender and recipient address information. Tarpitting qmqpd_error_sleep_time Time to wait in seconds before informing the client of a problem. This slows down run-away errors. SEE ALSO
