It takes + SMTP messages from the network and throws them away. The purpose is to + measure client performance, not protocol compliance. + + <b>smtp-sink</b> may also be configured to capture each mail delivery transac- + tion to file. Since disk latencies are large compared to network + delays, this mode of operation can reduce the maximal performance by + several orders of magnitude. + + Connections can be accepted on IPv4 or IPv6 endpoints, or on + UNIX-domain sockets. IPv4 and IPv6 are the default. This program is + the complement of the <a href="smtp-source.1.html"><b>smtp-source</b>(1)</a> program. + + Note: this is an unsupported test program. No attempt is made to main- + tain compatibility between successive versions. + + Arguments: + + <b>-4</b> Support IPv4 only. This option has no effect when Postfix is + built without IPv6 support. + + <b>-6</b> Support IPv6 only. This option is not available when Postfix is + built without IPv6 support. + + <b>-8</b> Do not announce 8BITMIME support. + + <b>-a</b> Do not announce SASL authentication support. + + <b>-A</b> <i>delay</i> + Wait <i>delay</i> seconds after responding to DATA, then abort prema- + turely with a 550 reply status. Do not read further input from + the client; this is an attempt to block the client before it + sends ".". Specify a zero delay value to abort immediately. + + <b>-b</b> <i>soft-bounce-reply</i> + Use <i>soft-bounce-reply</i> for soft reject responses. The default + reply is "450 4.3.0 Error: command failed". + + <b>-B</b> <i>hard-bounce-reply</i> + Use <i>hard-bounce-reply</i> for hard reject responses. The default + reply is "500 5.3.0 Error: command failed". + + <b>-c</b> Display running counters that are updated whenever an SMTP ses- + sion ends, a QUIT command is executed, or when "." is received. + + <b>-C</b> Disable XCLIENT support. + + <b>-d</b> <i>dump-template</i> + Dump each mail transaction to a single-message file whose name + is created by expanding the <i>dump-template</i> via strftime(3) and + appending a pseudo-random hexadecimal number (example: + "%Y%m%d%H/%M." expands into "2006081203/05.809a62e3"). If the + template contains "/" characters, missing directories are cre- + ated automatically. The message dump format is described below. + + Note: this option keeps one capture file open for every mail + transaction in progress. + + <b>-D</b> <i>dump-template</i> + Append mail transactions to a multi-message dump file whose name + is created by expanding the <i>dump-template</i> via strftime(3). If + the template contains "/" characters, missing directories are + created automatically. The message dump format is described + below. + + Note: this option keeps one capture file open for every mail + transaction in progress. + + <b>-e</b> Do not announce ESMTP support. + + <b>-E</b> Do not announce ENHANCEDSTATUSCODES support. + + <b>-f</b> <i>command,command,...</i> + Reject the specified commands with a hard (5xx) error code. + This option implies <b>-p</b>. + + Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT, + VRFY, DATA, ., RSET, NOOP, and QUIT. Separate command names by + white space or commas, and use quotes to protect white space + from the shell. Command names are case-insensitive. + + <b>-F</b> Disable XFORWARD support. + + <b>-h</b> <i>hostname</i> + Use <i>hostname</i> in the SMTP greeting, in the HELO response, and in + the EHLO response. The default hostname is "smtp-sink". + + <b>-H</b> <i>delay</i> + Delay the first read operation after receiving DATA (time in + seconds). Combine with a large test message and a small TCP win- + dow size (see the <b>-T</b> option) to test the Postfix client + write_wait() implementation. + + <b>-L</b> Enable LMTP instead of SMTP. + + <b>-m</b> <i>count</i> (default: 256) + An upper bound on the maximal number of simultaneous connections + that <b>smtp-sink</b> will handle. This prevents the process from run- + ning out of file descriptors. Excess connections will stay + queued in the TCP/IP stack. + + <b>-M</b> <i>count</i> + Terminate after receiving <i>count</i> messages. + + <b>-n</b> <i>count</i> + Terminate after <i>count</i> sessions. + + <b>-N</b> Do not announce support for DSN. + + <b>-p</b> Do not announce support for ESMTP command pipelining. + + <b>-P</b> Change the server greeting so that it appears to come through a + CISCO PIX system. Implies <b>-e</b>. + + <b>-q</b> <i>command,command,...</i> + Disconnect (without replying) after receiving one of the speci- + fied commands. + + Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT, + VRFY, DATA, ., RSET, NOOP, and QUIT.

Separate command names by + white space or commas, and use quotes to protect white space + from the shell. Command names are case-insensitive. + + <b>-r</b> <i>command,command,...</i> + Reject the specified commands with a soft (4xx) error code. + This option implies <b>-p</b>. + + Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT, + VRFY, DATA, ., RSET, NOOP, and QUIT. Separate command names by + white space or commas, and use quotes to protect white space + from the shell. Command names are case-insensitive. + + <b>-R</b> <i>root-directory</i> + Change the process root directory to the specified location. + This option requires super-user privileges. See also the <b>-u</b> + option. + + <b>-s</b> <i>command,command,...</i> + Log the named commands to syslogd. + + Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT, + VRFY, DATA, ., RSET, NOOP, and QUIT. Separate command names by + white space or commas, and use quotes to protect white space + from the shell. Command names are case-insensitive. + + <b>-S start-string</b> + An optional string that is prepended to each message that is + written to a dump file (see the dump file format description + below). The following C escape sequences are supported: \a + (bell), \b (backspace), \f (formfeed), \n (newline), \r (car- + riage return), \t (horizontal tab), \v (vertical tab), \<i>ddd</i> (up + to three octal digits) and \\ (the backslash character). + + <b>-t</b> <i>timeout</i> (default: 100) + Limit the time for receiving a command or sending a response. + The time limit is specified in seconds. + + <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>-u</b> <i>username</i> + Switch to the specified user privileges after opening the net- + work socket and optionally changing the process root directory. + This option is required when the process runs with super-user + privileges. See also the <b>-R</b> option. + + <b>-v</b> Show the SMTP conversations. + + <b>-w</b> <i>delay</i> + Wait <i>delay</i> seconds before responding to a DATA command. + + <b>-W</b> <i>command:delay[:odds]</i> + Wait <i>delay</i> seconds before responding to <i>command</i>. If <i>odds</i> is + also specified (a number between 1-99 inclusive), wait for a + random multiple of <i>delay</i>. The random multiplier is equal to the + number of times the program needs to roll a dice with a range of + 0..99 inclusive, before the dice produces a result greater than + or equal to <i>odds</i>. + + [<b>inet:</b>][<i>host</i>]:<i>port</i> + Listen on network interface <i>host</i> (default: any interface) TCP + port <i>port</i>. Both <i>host</i> and <i>port</i> may be specified in numeric or + symbolic form. + + <b>unix:</b><i>pathname</i> + Listen on the UNIX-domain socket at <i>pathname</i>. + + <i>backlog</i> + The maximum length of the queue of pending connections, as + defined by the <b>listen</b>(2) system call. + +<b>DUMP FILE FORMAT</b> + Each dumped message contains a sequence of text lines, terminated with + the newline character. The sequence of information is as follows: + + <b>o</b> The optional string specified with the <b>-S</b> option. + + <b>o</b> The <b>smtp-sink</b> generated headers as documented below. + + <b>o</b> The message header and body as received from the SMTP client. + + <b>o</b> An empty line. + + The format of the <b>smtp-sink</b> generated headers is as follows: + + <b>X-Client-Addr:</b> <i>text</i> + The client IP address without enclosing []. An IPv6 address is + prefixed with "ipv6:". This record is always present. + + <b>X-Client-Proto:</b> <i>text</i> + The client protocol: SMTP, ESMTP or LMTP. This record is always + present. + + <b>X-Helo-Args:</b> <i>text</i> + The arguments of the last HELO or EHLO command before this mail + delivery transaction. This record is present only if the client + sent a recognizable HELO or EHLO command before the DATA com- + mand. + + <b>X-Mail-Args:</b> <i>text</i> + The arguments of the MAIL command that started this mail deliv- + ery transaction. This record is present exactly once. + + <b>X-Rcpt-Args:</b> <i>text</i> + The arguments of an RCPT command within this mail delivery + transaction. There is one record for each RCPT command, and they + are in the order as sent by the client. + + <b>Received:</b> <i>text</i> + A message header for compatibility with mail processing soft- + ware. This three-line header marks the end of the headers pro- + vided by <b>smtp-sink</b>, and is formatted as follows: + + <b>from</b> <i>helo</i> ([<i>addr</i>]) + The HELO or EHLO command argument and client IP address. + If the client did not send HELO or EHLO, the client IP + address is used instead. + + <b>by</b> <i>host</i> <b>(smtp-sink) with</b> <i>proto</i> <b>id</b> <i>random</i><b>;</b> + The hostname specified with the <b>-h</b> option, the client + protocol (see <b>X-Client-Proto</b> above), and the pseudo-ran- + dom portion of the per-message capture file name. + + <i>time-stamp</i> + A time stamp as defined in <a href="https://tools.ietf.org/html/rfc2822">RFC 2822</a>. + +<b>SEE ALSO</b> + <a href="smtp-source.1.html">smtp-source(1)</a>, SMTP/LMTP message generator + +<b>LICENSE</b> + The Secure Mailer license must be distributed with this software. + +<b>AUTHOR(S)</b> + Wietse Venema + IBM T.J.
