QMQP-SINK(1) General Commands Manual 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
measure QMQP client performance, not protocol compliance. Connections can be accepted on IPv4 or IPv6 endpoints, or on UNIX-domain sock-
ets. 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 maintain 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 conversation.
-x time
Terminate after time seconds. This is to facilitate memory leak testing.

SMTP-SOURCE(1) General Commands Manual SMTP-SOURCE(1)NAME
smtp-source - multi-threaded SMTP/LMTP test generator
SYNOPSIS
smtp-source [options] [inet:]host[:port]
smtp-source [options] unix:pathname
DESCRIPTION
smtp-source connects to the named host and TCP port (default: port 25) and sends one or more messages to it, either sequentially or in par-
allel. The program speaks either SMTP (default) or LMTP. 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.
-A Don't abort when the server sends something other than the expected positive reply code.
-c Display a running counter that is incremented each time an SMTP DATA command 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.
-d Don't disconnect after sending a message; send the next message over the same connection.
-f from
Use the specified sender address (default: <foo@myhostname>).
-F file
Send the pre-formatted message header and body in the specified file, while prepending '.' before lines that begin with '.', and
while appending CRLF after each line.
-l length
Send length bytes as message payload. The length does not include message headers.
-L Speak LMTP rather than SMTP.
-m message_count
Send the specified number of messages (default: 1).
-M myhostname
Use the specified hostname or [address] in the HELO command and in the default sender and recipient addresses, instead of the
machine hostname.
-N Prepend a non-repeating sequence number to each recipient address. This avoids the artificial 100% hit rate in the resolve and re-
write client caches and exercises the trivial-rewrite daemon, better approximating Postfix performance under real-life work-loads.
-o Old mode: don't send HELO, and don't send message headers.
-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.
-R interval
Wait for a random period of time 0 <= n <= interval between messages. Suspending one thread does not affect other delivery threads.
-s session_count
Run the specified number of SMTP sessions in parallel (default: 1).
-S subject
Send mail with the named subject line (default: none).
-t to Use the specified recipient address (default: <foo@myhostname>).
-T windowsize
Override the default TCP window size. To work around broken TCP window scaling implementations, specify a value > 0 and < 65536.
-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.
[inet:]host[:port]
Connect via TCP to host host, port port. The default port is smtp.
unix:pathname
Connect to the UNIX-domain socket at pathname.
BUGS
No SMTP command pipelining support.
