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: &lt;foo@<a href="postconf.5.html#myhostname">myhostname</a>&gt;).

       <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 &lt;= n &lt;= 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: &lt;foo@<a href="postconf.5.html#myhostname">myhostname</a>&gt;).

       <b>-T</b> <i>windowsize</i>
              Override  the default TCP window size. To work around broken TCP
              window scaling implementations, specify a value &gt; 0 and &lt; 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.
