## NAME

milter-manager - an effective anti-spam and anti-virus solution with milters

## SYNOPSIS

`milter-manager` [ option ... ]

## DESCRIPTION

milter-manager is a milter that provides an effective anti-spam and anti-virus solution with milters.

milter-manager provides a platform to use milters effectively and flexibly. milter-manager has embedded Ruby interpreter that is used for dynamic milter applicable condition. milter-manager can provide the platform by embedded Ruby interpreter.

milter-manager reads its configuration file. The current configuration can be confirmed by --show-config option:

    % milter-manager --show-config

milter-manager also provides other options that overrides configurations specified in configuration file.

## 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:/var/run/milter/milter-manager.sock inet:10025 inet:10025@localhost inet:10025@[127.0.0.1] inet6:10025 inet6:10025@ip6-localhost inet6:10025@[::1] This option overrides "manager.connection_spec" in configuration file.
--config-dir=DIRECTORY | Specifies a directory that includes milter-manager's configuration file. milter-manager tries to load DIRECTORY/milter-manager.conf. If it isn't find, milter-manager loads milter-manager.conf in default directory.
--pid-file=FILE | Saves process ID of milter-manager to FILE. This option overrides "manager.pid_file" in configuration file.
--user-name=NAME | Runs milter-manager as NAME user. milter-manager should be started by root. This option overrides "security.effective_user" in configuration file.
--group-name=NAME | Runs milter-manager as NAME group. milter-manager should be started by root. This option overrides "security.effective_group" in configuration file.
--socket-group-name=NAME | Changes group of UNIX domain socket for accepting connection by milter-manager to NAME group. Specified group should be one of the effective user's supplementary groups. This option overrides "manager.unix_socket_group" in configuration file.
--daemon | Runs milter-manager as daemon process. This option overrides "manager.daemon" in configuration file.
--no-daemon | This option cancels the prior --daemon option.
--show-config | Shows the current configuration and exits. The output format can be used in configuration file. This option is useful for confirming registered milters and reporting your milter-manager's configuration when you report milter-manager's problems.
--log-level=LEVEL | Specifies log output items. You can specify multiple items by separating items with "|" like "error|warning|message". See Log list - Level for available levels.
--log-path=PATH | Specifies log output path. If you don't specify this option, log output is the standard output. You can use "-" to output to the standard output.
--event-loop-backend=BACKEDN | Uses `BACKEND` as event loop backend. Available values are glib or libev . If you use glib backend, please refer to the following note. NOTE: For the sake of improving milter-manager performance per process, event-driven model based architecture pattern is choosed in this software. If this feature is implemented by glib, it is expressed as a callback. Note that glib's callback registration upper limit makes the limitation of the number of communications. This limitations exist against glib backend only.
--verbose | Logs verbosely. Logs by syslog with "mail". If milter-manager isn't daemon process, standard output is also used. "--log-level=all" option has the same effect.
--version | Shows version and exits.

## EXIT STATUS

The exit status is 0 if milter starts to listen and non 0 otherwise. milter-manager 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.

## FILES

/usr/local/etc/milter-manager/milter-manager.conf | The default configuration file.

## SIGNALS

Milter-manager processes the following signals:

SIGHUP | Milter-manager reloads its configuration file.
SIGUSR1 | Milter-manager reopenes log file.

## EXAMPLE

The following example is good for debugging milter-manager behavior. In the case, milter-manager works in the foreground and logs are outputted to the standard output.

    % milter-manager --no-daemon --verbose
