       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

              table  prints a table header followed by adjusted value lines.

       -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.

       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 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.

       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 ex-
              ample  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 ac-
              cess  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 let-
              ters,  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

                     r -> read
                         Mailbox can be opened for reading.

                     w -> write

                     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 exist-
       ing 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

   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 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 exist-
       ing rights are replaced.
