       doveadm-acl - Manage Access Control List (ACL)

       doveadm [-Dv] [-f formatter] acl command [OPTIONS] [ARGUMENTS]

       The doveadm acl COMMANDS can be used to execute various Access Control List related actions.

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -f formatter
              Specifies the formatter for formatting the output.  Supported formatters are:

              flow   prints each line with key=value pairs.

              pager  prints  each key: value pair on its own line and separates records with form feed character (^L).

              tab    prints a table header followed by tab separated value lines.

              table  prints a table header followed by adjusted value lines.

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

       -v     Enables verbosity, including progress counter.

       This command uses by default the output formatter table.

       Command specific options:

       -A     If the -A option is present, the command will be performed for all users.  Using this option in combina-
              tion 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 iterate_query setting in /etc/dovecot/dove-
              cot-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.
              Otherwise doveadm(1) will be unable to iterate over all users.

       -F file
              Execute the command for all the users in the file.  This is similar 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 environment of the currently logged in user.

       id     The id (identifier) is one of:

                     *   group-override=group_name

                     *   user=user_name

                     *   owner

                     *   group=group_name

                     *   authenticated

                     *   anyone (or anonymous, which is an alias for anyone)

              The  ACLs are processed in the precedence given above, so for example if you have given read-access to a
              group, you can still remove that from specific users inside the group.
              Group-override identifier allows you to override users' ACLs.  Probably the most  useful  reason  to  do
              this is to temporarily disable access for some users.  For example:

              user=timo rw

              Now  if  timo  is a member of the tempdisabled group, he has no access to the mailbox.  This wouldn't be
              possible with a normal group identifier, because the user=timo would override it.

              The name of the mailbox, for which the ACL manipulation should be done.  It's also possible to  use  the
              wildcard characters "*" and/or "?" in the mailbox name.

       right  Dovecot  ACL  right name. This isn't the same as the IMAP ACL letters, which aren't currently supported.
              Here is a mapping of the IMAP ACL letters to Dovecot ACL names:

                     l --> lookup
                         Mailbox is visible in mailbox list.  Mailbox can be subscribed to.

                     r --> read
                         Mailbox can be opened for reading.

                     w --> write
                         Message flags and keywords can be changed, except \Seen and \Deleted.

                     s --> write-seen
                         \Seen flag can be changed.

                     t --> write-deleted
                         \Deleted flag can be changed.

                     i --> insert
                         Messages can be written or copied to the mailbox.

                     p --> post
                         Messages can be posted to the mailbox by dovecot-lda, e.g. from Sieve scripts.

                     e --> expunge
                         Messages can be expunged.

                     k --> create
                         Mailboxes can be created/renamed directly under this mailbox (but not necessarily  under  its
                         children, see ACL Inheritance in the wiki).
                         Note: Renaming also requires the delete right.

                     x --> delete
                         Mailbox can be deleted.

                     a --> admin
                         Administration rights to the mailbox (currently: ability to change ACLs for mailbox).

   acl add
       doveadm acl add [-u user|-A|-F file] [-S socket_path] mailbox id right [right ...]

       Add ACL rights to the mailbox/id.  If the id already exists, the existing rights are preserved.

   acl debug
       doveadm acl debug [-u user|-A|-F file] [-S socket_path] mailbox

       This command can be used to debug why a shared mailbox isn't accessible to the user.  It will list exactly what
       the problem is.

   acl delete
       doveadm acl delete [-u user|-A|-F file] [-S socket_path] mailbox id

       Remove the whole ACL entry for the mailbox/id.

   acl get
       doveadm acl get [-u user|-A|-F file] [-S socket_path] [-m] mailbox

       Show all the ACLs for the mailbox.

   acl recalc
       doveadm acl recalc [-u user|-A|-F file] [-S socket_path]

       Make sure the user's shared mailboxes exist correctly in the acl_shared_dict.

   acl remove
       doveadm acl remove [-u user|-A|-F file] [-S socket_path] mailbox id right [right ...]

       Remove the specified ACL rights from the mailbox/id.  If all rights are removed, the entry still exists without
       any rights.

   acl rights
       doveadm acl rights [-u user|-A|-F file] [-S socket_path] mailbox

       Show the user's current ACL rights for the mailbox.

   acl set
       doveadm acl set [-u user|-A|-F file] [-S socket_path] mailbox id right [right ...]

       Set ACL rights to the mailbox/id.  If the id already exists, the existing rights are replaced.
