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 dump [-a director_socket_path]
       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 connec-
       tions 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

   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@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.
