NAME
       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] [host]

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 AT 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
   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 purposes.

   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 mappings. Note that
       the director works using 32bit hashes which makes collisions quite likely, so this command
       can't reliably list exactly which users have recently logged in.

       -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 order to remove the given host from the director.

   director dump
       doveadm director dump [-a director_socket_path]

       Dump  the current host configuration as doveadm commands. These commands can be easily run
       after a full director cluster restart to get back to the dumped state.

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

       This command is used to show the current usage of all assigned mail servers.
       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.

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 AT 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 set‐
       tings). 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.
