+.SH DESCRIPTION
+.ad
+.fi
+\fBsmtp\-sink\fR listens on the named host (or address) and port.
+It takes SMTP messages from the network and throws them away.
+The purpose is to measure client performance, not protocol
+compliance.
+
+\fBsmtp\-sink\fR may also be configured to capture each mail
+delivery transaction 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 \fBsmtp\-source\fR(1) program.
+
+Note: this is an unsupported test program. No attempt is made
+to maintain compatibility between successive versions.
+
+Arguments:
+.IP \fB\-4\fR
+Support IPv4 only. This option has no effect when
+Postfix is built without IPv6 support.
+.IP \fB\-6\fR
+Support IPv6 only. This option is not available when
+Postfix is built without IPv6 support.
+.IP \fB\-8\fR
+Do not announce 8BITMIME support.
+.IP \fB\-a\fR
+Do not announce SASL authentication support.
+.IP "\fB\-A \fIdelay\fR"
+Wait \fIdelay\fR seconds after responding to DATA, then
+abort prematurely 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.
+.IP "\fB\-b \fIsoft\-bounce\-reply\fR"
+Use \fIsoft\-bounce\-reply\fR for soft reject responses.  The
+default reply is "450 4.3.0 Error: command failed".
+.IP "\fB\-B \fIhard\-bounce\-reply\fR"
+Use \fIhard\-bounce\-reply\fR for hard reject responses.  The
+default reply is "500 5.3.0 Error: command failed".
+.IP \fB\-c\fR
+Display running counters that are updated whenever an SMTP
+session ends, a QUIT command is executed, or when "." is
+received.
+.IP \fB\-C\fR
+Disable XCLIENT support.
+.IP "\fB\-d \fIdump\-template\fR"
+Dump each mail transaction to a single\-message file whose
+name is created by expanding the \fIdump\-template\fR 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 created automatically.  The message dump format is
+described below.
+.sp
+Note: this option keeps one capture file open for every
+mail transaction in progress.
+.IP "\fB\-D \fIdump\-template\fR"
+Append mail transactions to a multi\-message dump file whose
+name is created by expanding the \fIdump\-template\fR via
+strftime(3).
+If the template contains "/" characters, missing directories
+are created automatically.  The message dump format is
+described below.
+.sp
+Note: this option keeps one capture file open for every
+mail transaction in progress.
+.IP \fB\-e\fR
+Do not announce ESMTP support.
+.IP \fB\-E\fR
+Do not announce ENHANCEDSTATUSCODES support.
+.IP "\fB\-f \fIcommand,command,...\fR"
+Reject the specified commands with a hard (5xx) error code.
+This option implies \fB\-p\fR.
+.sp
+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.
+.IP \fB\-F\fR
+Disable XFORWARD support.
+.IP "\fB\-h\fI hostname\fR"
+Use \fIhostname\fR in the SMTP greeting, in the HELO response,
+and in the EHLO response. The default hostname is "smtp\-sink".
+.IP "\fB\-H\fI delay\fR"
+Delay the first read operation after receiving DATA (time
+in seconds). Combine with a large test message and a small
+TCP window size (see the \fB\-T\fR option) to test the Postfix
+client write_wait() implementation.
+.IP \fB\-L\fR
+Enable LMTP instead of SMTP.
+.IP "\fB\-m \fIcount\fR (default: 256)"
+An upper bound on the maximal number of simultaneous
+connections that \fBsmtp\-sink\fR will handle. This prevents
+the process from running out of file descriptors. Excess
+connections will stay queued in the TCP/IP stack.
+.IP "\fB\-M \fIcount\fR"
+Terminate after receiving \fIcount\fR messages.
+.IP "\fB\-n \fIcount\fR"
+Terminate after \fIcount\fR sessions.
+.IP \fB\-N\fR
+Do not announce support for DSN.
+.IP \fB\-p\fR
+Do not announce support for ESMTP command pipelining.
+.IP \fB\-P\fR
+Change the server greeting so that it appears to come through
+a CISCO PIX system. Implies \fB\-e\fR.
+.IP "\fB\-q \fIcommand,command,...\fR"
+Disconnect (without replying) after receiving one of the
+specified commands.
+.sp
+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.
+.IP "\fB\-Q \fIcommand,command,...\fR"
+Send a 421 reply and disconnect after receiving one
+of the specified commands.
+.sp
+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.
+.IP "\fB\-r \fIcommand,command,...\fR"
+Reject the specified commands with a soft (4xx) error code.
+This option implies \fB\-p\fR.
+.sp
+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.
+.IP "\fB\-R \fIroot\-directory\fR"
+Change the process root directory to the specified location.
+This option requires super\-user privileges. See also the
+\fB\-u\fR option.
+.IP "\fB\-s \fIcommand,command,...\fR"
+Log the named commands to syslogd.
+.sp
+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.
+.IP "\fB\-S start\-string\fR"
+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: \ea
+(bell), \eb (backspace), \ef (formfeed), \en (newline), \er
+(carriage return), \et (horizontal tab), \ev (vertical tab),
+\e\fIddd\fR (up to three octal digits) and \e\e (the backslash
+character).
+.IP "\fB\-t \fItimeout\fR (default: 100)"
+Limit the time for receiving a command or sending a response.
+The time limit is specified in seconds.
+.IP "\fB\-T \fIwindowsize\fR"
+Override the default TCP window size. To work around
+broken TCP window scaling implementations, specify a
+value > 0 and < 65536.
+.IP "\fB\-u \fIusername\fR"
+Switch to the specified user privileges after opening the
+network socket and optionally changing the process root
+directory. This option is required when the process runs
+with super\-user privileges. See also the \fB\-R\fR option.
+.IP \fB\-v\fR
+Show the SMTP conversations.
+.IP "\fB\-w \fIdelay\fR"
+Wait \fIdelay\fR seconds before responding to a DATA command.
+.IP "\fB\-W \fIcommand:delay[:odds]\fR"
+Wait \fIdelay\fR seconds before responding to \fIcommand\fR.
+If \fIodds\fR is also specified (a number between 1\-99
+inclusive), wait for a random multiple of \fIdelay\fR. 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 \fIodds\fR.
+.IP [\fBinet:\fR][\fIhost\fR]:\fIport\fR
+Listen on network interface \fIhost\fR (default: any interface)
+TCP port \fIport\fR. Both \fIhost\fR and \fIport\fR may be
+specified in numeric or symbolic form.
+.IP \fBunix:\fR\fIpathname\fR
+Listen on the UNIX\-domain socket at \fIpathname\fR.

+The optional string specified with the \fB\-S\fR option.
+.IP \(bu
+The \fBsmtp\-sink\fR generated headers as documented below.
+.IP \(bu
+The message header and body as received from the SMTP client.
+.IP \(bu
+An empty line.
+.PP
+The format of the \fBsmtp\-sink\fR generated headers is as
+follows:

+The arguments of the MAIL command that started this mail
+delivery transaction. This record is present exactly once.
+.IP "\fBX\-Rcpt\-Args: \fItext\fR"
