NAME¶

doveadm-director - Manage Dovecot directors

SYNOPSIS¶

doveadm [-Dv] director add [-a director_socket_path] host [vhost_count]
doveadm [-Dv] director flush [-a director_socket_path] host|all
doveadm [-Dv] director map [-a director_socket_path] [-f users_file] [host]
doveadm [-Dv] director remove [-a director_socket_path] host
doveadm [-Dv] director status [-a director_socket_path] [user]

DESCRIPTION¶

doveadm director can be used to manage and query the status of the list of backend mail servers where Dovecot proxy can redirect connections to.

OPTIONS¶

Global doveadm(1) options:

-D

Enables verbosity and debug messages.

-v

Enables verbosity, including progress counter.

Command specific options:

-a director_socket_path

This option is used to specify an alternative socket. The option's argument is either an absolute path to a local UNIX domain socket, or a hostname and port (hostname:port), in order to connect a remote host via a TCP socket.

By default doveadm(1) will use the socket /var/run/dovecot/director-admin. The socket may be located in another directory, when the default base_dir setting was overridden in /etc/dovecot/dovecot.conf.

ARGUMENTS¶

host

A mail server's hostname or IP address.

user

Is a user's login name. Depending on the configuration, a login name may be for example jane or john@example.com.

vhost_count

The number of "virtual hosts" to assign to this server. The higher the number is relative to other servers, the more connections it gets. The default is 100.

COMMANDS¶

FILES¶

/etc/dovecot/dovecot.conf

Dovecot's main configuration file.

/etc/dovecot/conf.d/10-director.conf

Director specific settings.

EXAMPLE¶

Add a director with vhost count 150 (or change existing one's vhost count to 150):

doveadm -v director add x1357.imap.ha.example.net 150
2001:db8:543:6861:143::1357: OK

Remove a director:

doveadm director remove x1357.imap.ha.example.net

Query the status of mail hosts in a director:

doveadm director status
mail server ip       vhosts  users
192.168.10.1            100    125
192.168.10.2            100    144
192.168.10.3            100    115

Query the status of a user's assignment:

doveadm director status user@example.com
Current: 192.168.10.1 (expires 2010-06-18 20:17:04)
Hashed: 192.168.10.2
Initial config: 192.168.10.3

This means that the user is currently assigned to mail server on IP 192.168.10.1. After all of user's connections have logged out, the assignment will be removed (currently it looks like at 20:17:04, but that may be increased). After the assignment has expired, the user will next time be redirected to 192.168.10.2 (assuming no changes to director settings). If the entire Dovecot proxy cluster was restarted, so that all of the director configuration would revert back to its initial values, the user would be redirected to 192.168.10.3.
