SMTP-SINK(1)                                                      SMTP-SINK(1)

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 endpoints or UNIX-domain sockets.
       IPV4 is the default.  This program  is  the  complement  of  the  smtp-
       source(1) program.

       Arguments:

       -a     Do not announce SASL authentication support.

       -c     Display  a running counter that is updated whenever an SMTP QUIT
              command is executed.

       -C     Disable XCLIENT support.

       -e     Do not announce ESMTP support.

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

       -F     Disable XFORWARD support.

       -h     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.

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

       -s command,command,...
              Log  the  named  commands to syslogd.  Examples of commands that
              can be logged are HELO, EHLO,  LHLO,  MAIL,  RCPT,  VRFY,  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.

       -v     Show the SMTP conversations.

       -w delay
              Wait delay seconds before responding to a DATA command.

       -8     Do not announce 8BITMIME support.

       [inet:][host]:port
              Listen  on  network  interface host (default: any interface) TCP
              port port. Both host and port may be  specified  in  numeric  or
              symbolic form.

       unix:pathname
              Listen on the UNIX-domain socket at pathname.

       backlog
              The  maximum length the queue of pending connections, as defined
              by the listen(2) call.
