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 <foo@<a href="postconf.5.html#myhostname">myhostname</a>>). 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 <= n <= 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 <foo@<a href="postconf.5.html#myhostname">myhostname</a>>). 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 > 0 and < 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. 130 131<b>SEE ALSO</b> 132 <a href="smtp-sink.1.html">smtp-sink(1)</a>, SMTP/LMTP message dump 133 134<b>LICENSE</b> 135 The Secure Mailer license must be distributed with this 136 software. 137 138<b>AUTHOR(S)</b> 139 Wietse Venema 140 IBM T.J.
