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 session 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

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.

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.
