NAME

SYNOPSIS

DESCRIPTION

OPTIONS

-D

Enables verbosity and debug messages.

-o setting=value

Overrides the configuration setting from /usr/local/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 /usr/local/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 /usr/local/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.
