## milter-test-client milter-test-client — milter side milter protocol implemented program |

## NAME

milter-test-client - milter side milter protocol implemented program

## SYNOPSIS

`milter-test-client` [ option ... ]

## DESCRIPTION

milter-test-client is a milter that just shows received data from MTA. It also shows macros received from MTA, it can be used for confirming MTA's milter configuration.

Postfix's source archive includes similar tool. It's src/milter/test-milter.c. It seems that it's used for testing Postfix's milter implementation. But test-milter doesn't show macros. If you have a milter that doesn't work as you expect and uses macro, milter-test-client is useful tool for looking into the problems.

## Options

--help | Shows available options and exits.
--connection-spec=SPEC | Specifies a socket that accepts connections from MTA. SPEC should be formatted as one of the followings: unix:PATH inet:PORT inet:PORT@HOST inet:PORT@[ADDRESS] inet6:POST inet6:PORT@HOST inet6:PORT@[ADDRESS] Examples: unix:/tmp/milter-test-client.sock inet:10025 inet:10025@localhost inet:10025@[127.0.0.1] inet6:10025 inet6:10025@localhost inet6:10025@[::1]
--verbose | Logs verbosely. "MILTER_LOG_LEVEL=all" environment variable configuration has the same effect.
--syslog | Logs Syslog too.
--no-report-request | Doesn't show any information received from MTA.
--report-memory-profile | Reports memory usage each milter session finished. When MILTER_MEMORY_PROFILE environment variable is set to 'yes', details are reported. Example:
    % MILTER_MEMORY_PROFILE=yes milter-test-client -s inet:10025
--daemon | Runs as daemon process.
--user=USER | Runs as USER's process. root privilege is needed.
--group=GROUP | Runs as GROUP's process. root privilege is needed.
--unix-socket-group=GROUP | Changes UNIX domain socket group to GROUP when "unix:PATH" format SPEC is used.
--n-workers=N_WORKERS | Runs `N_WORKERS` processes to process mails. Availble value is between 0 and 1000. If it is 0, no worker processes will be used. NOTE: This item is an experimental feature.
--event-loop-backend=BACKEDN | Uses `BACKEND` as event loop backend. Availble values are glib or libev . NOTE: This item is an experimental feature.
--packet-buffer-size=SIZE | Uses `SIZE` as send packets buffer size on end-of-message. Buffered packets are sent when buffer size is rather than `SIZE` bytes. Buffering is disabled when `SIZE` is 0. The default is 0KB. It means packet buffering is disabled by default.
--version | Shows version and exits.

## EXIT STATUS

The exit status is 0 if milter starts to listen and non 0 otherwise. milter-test-client can't start to listen when connection spec is invalid format or other connection specific problems. e.g. the port number is already used, permission isn't granted for create UNIX domain socket and so on.

## EXAMPLE

The following example runs a milter which listens at 10025 port and waits a connection from MTA.

    % milter-test-client -s inet:10025
