a></
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@my-hostname>).
<
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>my-hostname</
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> Generate each recipient
address by appending
a number (
a
per-process recipient counter) to the recipient
address local-
part specified with the <
b>-t</
b>
option.
Note: to use the number as an
address extension, specify an
explicit
address delimiter at the end of the recipient local-
part, as in
"<b>-t localpart+@domain</b>" or
"<b>-t localpart+</b>", where
"<b>+</b>"
is
a Postfix recipient
address delimiter.
Benefits:
<
b>o</
b> A non-constant recipient
address avoids an unrealistic
100% cache hit rate in clients of the Postfix trivial-re-
write service, better approximating performance under
real-life work-loads.
<
b>o</
b> A fixed recipient
address local-part with
a non-constant
address extension avoids the need to configure
a large
number of valid recipient addresses in the receiving
Postfix server.
<
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), and generate recipient addresses as described
under the <
b>-N</
b>
option.
<
b>-R</
b> <
i>interval</
i>
Wait
a random
time (
0 <= n <= <
i>interval</
i>) between messages. Sus-
pending 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@my-host-
name>).
<
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</

Connect to the UNIX-domain socket at <
