       doveadm-director - Manage Dovecot directors

       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]
       doveadm [-Dv] director remove [-a director_socket_path] host
       doveadm [-Dv] director status [-a director_socket_path] [user]

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

       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.

       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

              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.

   director add
       doveadm director add [-a director_socket_path] host [vhost_count]

       The command's tasks are:

       *   assign a new mail server to the director.

       *   increase/decrease the vhost_count of an already assigned server.

   director flush
       doveadm director flush [-a director_socket_path] host|all

       doveadm director flush drops all user associations either from the
       given host or all hosts.  This command is intended mainly for testing

   director map
       doveadm director map [-a director_socket_path] [-f users_file] [host]

       The command doveadm director map is used to list current user host

       -f users_file
              Path to a file containing all user names (one per line).  When
              given no userdb lookup will be performed.  This may be a helpful
              alternative when for example the network connection to the LDAP
              or SQL server is slow.

       host   Specify a server's IP address or hostname, to list only mappings
              of the given host.

   director remove
       doveadm director remove [-a director_socket_path] host

       Use this command in oder to remove the given host from the director.

   director status
       doveadm director status [-a director_socket_path] [user]

       This command is used to show the current usage of all assigned mail
       When a user name is given, this command shows which server the user is
       currently assigned to, where the user will be assigned after the
       current saved assignment gets removed and where the user would be
       assigned to if the whole proxy cluster was restarted fresh.

              Dovecot's main configuration file.

              Director specific settings.

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

       doveadm -v director add 150
       2001:db8:543:6861:143::1357: OK

       Remove a director:

       doveadm director remove

       Query the status of mail hosts in a director:

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

       Query the status of a user's assignment:

       doveadm director status
       Current: (expires 2010-06-18 20:17:04)
       Initial config:

       This means that the user is currently assigned to mail server on IP 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 (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
