doveadm-deduplicate


SYNOPSIS
       doveadm   [-Dv]   deduplicate   [-u   user|-A]  [-S  socket_path]  [-m]
       search_query

DESCRIPTION
       This command is used  to  expunge  duplicated  messages  in  mailboxes.
       doveadm  deduplicate  is  mainly  useful  to revert some (more or less)
       accidental duplication of messages, e.g. after doveadm copy or  doveadm
       import.  doveadm(1) will delete the newest duplicated messages from the
       mailbox and keep the oldest.
       Deduplication across multiple mailboxes is not supported.

OPTIONS
       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -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.

       -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.

       -m     if the -m option is given, doveadm(1) will deduplicate  by  Mes-
              sage-Id  header.   By default deduplication will be done by mes-
              sage GUIDs.

       -u user/mask
              Run the command only for the given user.  It's also possible  to
              use '*' and '?' wildcards (e.g. -u *@example.org).
              When  neither  the -A option nor -u user was specified, the com-
              mand will be executed with  the  environment  of  the  currently
              logged in user.
