SMTP-SOURCE(1) SMTP-SOURCE(1)
<b>NAME</b>
smtp-source - parallelized SMTP/LMTP test generator
<b>SYNOPSIS</b>
<b>smtp-source</b> [<i>options</i>] [<b>inet:</b>]<i>host</i>[:<i>port</i>]
<b>smtp-source</b> [<i>options</i>] <b>unix:</b><i>pathname</i>
<b>DESCRIPTION</b>
<b>smtp-source</b> connects to the named <i>host</i> and TCP <i>port</i> (default: port 25)
and sends one or more messages to it, either sequentially or in paral-
lel. 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 main-
tain compatibility between successive versions.
Arguments:
<b>-4</b> Connect to the server with IPv4. This option has no effect when
Postfix is built without IPv6 support.
<b>-6</b> Connect to the server with IPv6. This option is not available
when Postfix is built without IPv6 support.
<b>-A</b> Don't abort when the server sends something other than the
expected positive reply code.
<b>-c</b> Display a running counter that is incremented each time an SMTP
DATA command completes.
<b>-C</b> <i>count</i>
When a host sends RESET instead of SYN|ACK, try <i>count</i> 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.
<b>-d</b> Don't disconnect after sending a message; send the next message
over the same connection.
<b>-f</b> <i>from</i>
Use the specified sender address (default: <foo@<a href="postconf.5.html#myhostname">myhostname</a>>).
<b>-F</b> <i>file</i>
Send the pre-formatted message header and body in the specified
<i>file</i>, while prepending '.' before lines that begin with '.', and
while appending CRLF after each line.
<b>-l</b> <i>length</i>
Send <i>length</i> bytes as message payload. The length does not
include message headers.
<b>-L</b> Speak LMTP rather than SMTP.
<b>-m</b> <i>message</i><b>_</b><i>count</i>
Send the specified number of messages (default: 1).
<b>-M</b> <i><a href="postconf.5.html#myhostname">myhostname</a></i>
Use the specified hostname or [address] in the HELO command and
in the default sender and recipient addresses, instead of the
machine hostname.
<b>-N</b> Prepend a non-repeating sequence number to each recipient
address. This avoids the artificial 100% hit rate in the resolve
and rewrite client caches and exercises the trivial-rewrite dae-
mon, better approximating Postfix performance under real-life
work-loads.
<b>-o</b> Old mode: don't send HELO, and don't send message headers.
<b>-r</b> <i>recipient</i><b>_</b><i>count</i>
Send the specified number of recipients per transaction
(default: 1). Recipient names are generated by prepending a
number to the recipient address.
<b>-R</b> <i>interval</i>
Wait for a random period of time 0 <= n <= interval between mes-
sages. Suspending one thread does not affect other delivery
threads.
<b>-s</b> <i>session</i><b>_</b><i>count</i>
Run the specified number of SMTP sessions in parallel (default:
1).
<b>-S</b> <i>subject</i>
Send mail with the named subject line (default: none).
<b>-t</b> <i>to</i> Use the specified recipient address (default: <foo@<a href="postconf.5.html#myhostname">myhostname</a>>).
<b>-T</b> <i>windowsize</i>
Override the default TCP window size. To work around broken TCP
window scaling implementations, specify a value > 0 and < 65536.
<b>-v</b> Make the program more verbose, for debugging purposes.
<b>-w</b> <i>interval</i>
Wait a fixed time between messages. Suspending one thread does
not affect other delivery threads.
[<b>inet:</b>]<i>host</i>[:<i>port</i>]
Connect via TCP to host <i>host</i>, port <i>port</i>. The default port is
<b>smtp</b>.
<b>unix:</b><i>pathname</i>
Connect to the UNIX-domain socket at <i>pathname</i>.
<b>BUGS</b>
No SMTP command pipelining support.
