SMTP-SINK(1)SMTP-SINK(1)NAMEsmtp-sink - multi-threaded SMTP/LMTP test server
SYNOPSISsmtp-sink [options] [inet:][host]:port backlog
smtp-sink [options] unix:pathname backlog
DESCRIPTIONsmtp-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.

fied commands.
Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT,
VRFY, DATA, ., RSET, NOOP, and QUIT. Separate command names by

This option implies -p.
Examples of commands are CONNECT, HELO, EHLO, LHLO, MAIL, RCPT,
