       The  command  doveadm batch is used to execute multiple doveadm(1) com-
       mands sequentially for multiple users.  This is primarily an  optimiza-
       tion  where Dovecot can do all the mailbox operations for the same user
       at once, instead of having to go through the users multiple times.

       In the first form doveadm(1) will loop over all users, defined  in  the
       configured user_db(s), and execute the sequence of commands for each of

       In the second form doveadm(1) will loop over all users, listed  in  the
       given file.

       In  the third form the commands will be executed for each user matching
       the given usermask.

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -o setting=value
              Overrides  the  configuration  setting  from  /etc/dovecot/dove-
              cot.conf  and from the userdb with the given value.  In order to
              override multiple settings, the -o option may be specified  mul-
              tiple times.

       -v     Enables verbosity, including progress counter.

       Command specific options:

       -A     If  the  -A option is present, the command will be performed for
              all users.  Using this option in combination with  system  users
              from  userdb  { driver = passwd } is not recommended, because it
              contains also users with a lower UID  than  the  one  configured
              with the first_valid_uid setting.

              When  the  SQL  userdb  module  is used make sure that the iter-
              ate_query setting in  /etc/dovecot/dovecot-sql.conf.ext  matches
              your  database  layout.  When using the LDAP userdb module, make
              sure that  the  iterate_attrs  and  iterate_filter  settings  in
              /etc/dovecot/dovecot-ldap.conf.ext match your LDAP schema.  Oth-
              erwise doveadm(1) will be unable to iterate over all users.

       -F file
              Execute the command for all the users in the file.  This is sim-
              ilar  to the -A option, but instead of getting the list of users
              from the userdb, they are read from the given  file.   The  file
              contains one username per line.

       -S socket_path
              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.

              This allows an administrator to execute doveadm(1) mail commands
              through the given socket.

       -u user/mask
              Run the command only for the given user.  It's also possible  to
              use '*' and '?' wildcards (e.g. -u *
              When  neither  the  -A  option,  nor the -F file option, nor the
              -u user was specified, the command will be executed with the en-
              vironment of the currently logged in user.

              Any doveadm(1) command, with arguments and options -- except for
              the -A, -S and -u options.

       sep    A single character used as  command  separator,  e.g.  ':'.   Be
              careful, unquoted characters, like ; or &, may be interpreted by
              your shell and doveadm(1) will never see them.

       In this example we move seen mails, older than one month, for all exam- users to the alternative storage under /nfsmount:
       mail_location = mdbox:~/mdbox:ALT=/nfsmount/%h/mdbox
       The  second  command will remove messages with refcount=0 from the pri-
       mary storage.

       doveadm batch -u \* : altmove seen savedbefore 30d : purge
