DOVEADM-DEDUPLICATE(1)              Dovecot             DOVEADM-DEDUPLICATE(1)

NAME
       doveadm-deduplicate - expunge duplicate messages
SYNOPSIS
       doveadm  [-Dv]  deduplicate  [-u user|-A|-F file] [-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.
       -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.
       -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 the -F file option, nor the
              -u user was specified, the command will  be  executed  with  the
              environment of the currently logged in user.
ARGUMENTS
       search_query
              expunge duplicates found from messages matching the given search
              query.  Typically a search query like 'mailbox  mailbox_name  OR
              mailbox      other_box'     will     be     sufficient.      See
              doveadm-search-query(7) for details.
EXAMPLE
       This example shows how to list and expunge duplicate  messages  from  a
       mailbox.
       doveadm -f table fetch -u jane 'guid uid' mailbox a_Box | sort
       guid                             uid
       8aad0f0a30169f4bea620000ca356bad 18751
       8aad0f0a30169f4bea620000ca356bad 18756
       923e301ab9219b4b4f440000ca356bad 18748
       923e301ab9219b4b4f440000ca356bad 18753
       ...
       doveadm deduplicate -u jane mailbox a_Box
       doveadm -f table fetch -u jane 'guid uid' mailbox a_Box | sort
       guid                             uid
       8aad0f0a30169f4bea620000ca356bad 18751
