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/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.

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 iterate_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. 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.

-m if the -m option is given, doveadm(1) will deduplicate by Message-Id header. By
default deduplication will be done by message 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
