NAME
       smtp-sink - multi-threaded SMTP/LMTP test server

SYNOPSIS
       smtp-sink [options] [inet:][host]:port backlog

       smtp-sink [options] unix:pathname backlog

DESCRIPTION
       smtp-sink  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.

       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 smtp-source(1) program.

       Arguments:

       -4     Support  IPv4  only.  This  option has no effect when Postfix is
	      built without IPv6 support.

       -6     Support IPv6 only. This option is not available when Postfix  is
	      built without IPv6 support.

       -8     Do not announce 8BITMIME support.

       -a     Do not announce SASL authentication support.

       -c     Display  running counters that are updated whenever an SMTP ses
	      sion ends, a QUIT command is executed, or when "." is  received.

       -C     Disable XCLIENT support.

       -e     Do not announce ESMTP support.

       -E     Do not announce ENHANCEDSTATUSCODES support.

       -f command,command,...
	      Reject  the  specified  commands	with  a hard (5xx) error code.
	      This option implies -p.

	      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.

       -F     Disable XFORWARD support.

       -h hostname
	      Use  hostname in the SMTP greeting, in the HELO response, and in
	      the EHLO response. The default hostname is "smtp-sink".

       -L     Enable LMTP instead of SMTP.

       -n count
	      Terminate after count sessions. This is for testing purposes.

       -p     Do not announce support for ESMTP command pipelining.

       -P     Change the server greeting so that it appears to come through  a
	      CISCO PIX system. Implies -e.

       -q command,command,...
	      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.

       -r command,command,...
	      Reject  the  specified  commands	with  a soft (4xx) error code.
	      This option implies -p.

	      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.

       -s command,command,...
	      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

	      from the shell. Command names are case-insensitive.

       -t timeout (default: 100)
	      Limit the time for receiving a command or  sending  a  response.

	      Listen on the UNIX-domain socket at pathname.

       backlog
	      The  maximum length the queue of pending connections, as defined
