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:
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/dove-
cot/director-admin. The socket may be located in another direc-
tory, when the default base_dir setting was overridden in
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 email@example.com.
The number of "virtual hosts" to assign to this server. The
higher the number is relative to other servers, the more connec-
tions it gets. The default is 100.
doveadm director add [-a director_socket_path] host [vhost_count]
The command's tasks are:
* assign a new mail server to the director.
The command doveadm director map is used to list current user -> host
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.
doveadm director remove [-a director_socket_path] host
Use this command in order to remove the given host from the director.
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.
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 cur-
rent 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 x1357.imap.ha.example.net 150
Remove a director:
doveadm director remove x1357.imap.ha.example.net
Query the status of mail hosts in a director:
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 direc-
tor 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.
