   9 <b>NAME</b>
  10        smtp-source - multi-threaded SMTP/LMTP test generator
  11
  12 <b>SYNOPSIS</b>
  13        <b>smtp-source</b> [<i>options</i>] [<b>inet:</b>]<i>host</i>[:<i>port</i>]
  14
  15        <b>smtp-source</b> [<i>options</i>] <b>unix:</b><i>pathname</i>
  16
  17 <b>DESCRIPTION</b>
  18        <b>smtp-source</b>  connects  to  the  named  <i>host</i>  and  TCP <i>port</i>
  19        (default: port 25) and sends one or more messages  to  it,
  20        either  sequentially  or  in  parallel. The program speaks
  21        either SMTP (default) or LMTP.  Connections can be made to
  22        UNIX-domain  and  IPv4 or IPv6 servers.  IPv4 and IPv6 are
  23        the default.
  24
  25        Note: this is an unsupported test program. No  attempt  is
  26        made  to  maintain  compatibility  between successive ver-
  27        sions.
  28
  29        Arguments:
  30
  31        <b>-4</b>     Connect to the server with IPv4. This option has no
  32               effect  when Postfix is built without IPv6 support.
  33
  34        <b>-6</b>     Connect to the server with IPv6. This option is not
  35               available  when  Postfix is built without IPv6 sup-
  36               port.
  37
  38        <b>-A</b>     Don't abort when the server sends  something  other
  39               than the expected positive reply code.
  40
  41        <b>-c</b>     Display  a running counter that is incremented each
  42               time an SMTP DATA command completes.
  43
  44        <b>-C</b> <i>count</i>
  45               When a host sends RESET  instead  of  SYN|ACK,  try
  46               <i>count</i>  times before giving up. The default count is
  47               1. Specify a larger count in order to work around a
  48               problem with TCP/IP stacks that send RESET when the
  49               listen queue is full.
  50
  51        <b>-d</b>     Don't disconnect after sending a message; send  the
  52               next message over the same connection.
  53
  54        <b>-f</b> <i>from</i>
  55               Use   the   specified   sender   address  (default:
  56               &lt;foo@<a href="postconf.5.html#myhostname">myhostname</a>&gt;).
  57
  58        <b>-F</b> <i>file</i>
  59               Send the pre-formatted message header and  body  in
  60               the  specified  <i>file</i>,  while  prepending '.' before
  61               lines that begin with '.', and while appending CRLF
  62               after each line.
  63
  64        <b>-l</b> <i>length</i>
  65               Send  <i>length</i>  bytes  as message payload. The length
  66               does not include message headers.
  67
  68        <b>-L</b>     Speak LMTP rather than SMTP.
  69
  70        <b>-m</b> <i>message</i><b>_</b><i>count</i>
  71               Send the specified number of messages (default: 1).
  72
  73        <b>-M</b> <i><a href="postconf.5.html#myhostname">myhostname</a></i>
  74               Use the specified hostname or [address] in the HELO
  75               command and in the  default  sender  and  recipient
  76               addresses, instead of the machine hostname.
  77
  78        <b>-N</b>     Prepend  a  non-repeating  sequence  number to each
  79               recipient address. This avoids the artificial  100%
  80               hit  rate  in the resolve and rewrite client caches
  81               and exercises the  trivial-rewrite  daemon,  better
  82               approximating  Postfix  performance under real-life
  83               work-loads.
  84
  85        <b>-o</b>     Old mode: don't send HELO, and don't  send  message
  86               headers.
  87
  88        <b>-r</b> <i>recipient</i><b>_</b><i>count</i>
  89               Send  the specified number of recipients per trans-
  90               action (default: 1).  Recipient names are generated
  91               by prepending a number to the recipient address.
  92
  93        <b>-R</b> <i>interval</i>
  94               Wait for a random period of time 0 &lt;= n &lt;= interval
  95               between messages.  Suspending one thread  does  not
  96               affect other delivery threads.
  97
  98        <b>-s</b> <i>session</i><b>_</b><i>count</i>
  99               Run the specified number of SMTP sessions in paral-
 100               lel (default: 1).
 101
 102        <b>-S</b> <i>subject</i>
 103               Send mail with the  named  subject  line  (default:
 104               none).
 105
 106        <b>-t</b> <i>to</i>  Use   the  specified  recipient  address  (default:
 107               &lt;foo@<a href="postconf.5.html#myhostname">myhostname</a>&gt;).
 108
 109        <b>-T</b> <i>windowsize</i>
 110               Override the  default  TCP  window  size.  To  work
 111               around  broken  TCP window scaling implementations,
 112               specify a value &gt; 0 and &lt; 65536.
 113
 114        <b>-v</b>     Make the program more verbose, for  debugging  pur-
 115               poses.
 116
 117        <b>-w</b> <i>interval</i>
 118               Wait a fixed time between messages.  Suspending one
 119               thread does not affect other delivery threads.
 120
 121        [<b>inet:</b>]<i>host</i>[:<i>port</i>]
 122               Connect via  TCP  to  host  <i>host</i>,  port  <i>port</i>.  The
 123               default port is <b>smtp</b>.
 124
 125        <b>unix:</b><i>pathname</i>
 126               Connect to the UNIX-domain socket at <i>pathname</i>.
 127
 128 <b>BUGS</b>
 129        No SMTP command pipelining support.
