NAME

doveadm-mailbox - Commands related to handling mailboxes

SYNOPSIS

doveadm [GLOBAL OPTIONS] [-f formatter] mailbox_cmd [OPTIONS] [ARGUMENTS]

DESCRIPTION

doveadm mailbox can be used to query and modify mailboxes.

GLOBAL OPTIONS

Global doveadm(1)

-D

Enables verbosity and debug messages.

-O

Do not read any config file, just use defaults. The dovecot_storage_version setting defaults to the latest version, but can be overridden with

-k

Preserve entire environment for doveadm, not just import_environment setting.

-v

Enables verbosity, including progress counter.

-i instance-name

If using multiple Dovecot instances, choose the config file based on this instance name.

See instance_name setting for more information.

-c config-file

Read configuration from the given config-file. By default it first reads config socket, and then falls back to /etc/dovecot/dovecot.conf. You can also point this to config socket of some instance running compatible version.

-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.

-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 lines.

table

prints a table header followed by adjusted value lines.

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 userdb_sql_iterate_query setting setting matches your database layout.

When using the LDAP userdb module, make sure that the userdb_fields setting and userdb_ldap_iterate_fields setting settings 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.

--no-userdb-lookup

Do not perform userdb lookup. Use the USER environment variable to specify the username.

-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 *@example.org).

ARGUMENTS

mailbox

Is the name of a mailbox, as visible to IMAP clients, except in UTF-8 format. The hierarchy separator between a parent and child mailbox is commonly '/' or '.', but this depends on your selected mailbox storage format and namespace configuration. The mailbox names may also require a namespace prefix.

COMMANDS

mailbox create

doveadm [GLOBAL OPTIONS] mailbox create [-A | -u user | -F file | --no-userdb-lookup] [-S socket_path] [-g guid] [-s] mailbox...

This command is used to create one or more mailboxes. The mailbox format of the created mailboxes depends on the mail_driver setting, or the user's mail field, returned by the userdb.

-g guid

Create the mailbox with the specified GUID.

-s

When this option was given, the created mailboxes will be also added to the user's subscriptions.

mailbox cryptokey

doveadm [GLOBAL OPTIONS] mailbox cryptokey export|generate|list|password

This command is used to manage mail crypt plugin cryptographic keys. Please see doveadm-mailbox-cryptokey(1) for more details.

mailbox delete

doveadm [GLOBAL OPTIONS] mailbox delete [-A | -u user | -F file | --no-userdb-lookup] [-S socket_path] [-s] [-r] [-e] [-Z] mailbox...

This command deletes a mailbox and expunges all the messages it contains. If the mailbox has any children, they won't be deleted, unless -r is given.

-r

Delete mailboxes recursively

-s

Unsubscribe deleted mailboxes.

-e

Require mailboxes to be empty before deleting.

-Z

Delete the mailbox as efficiently as possible, but the user may not be in fully consistent state afterwards. For example quota may be wrong. This option is mainly useful when deleting the entire user.

mailbox list

doveadm [GLOBAL OPTIONS] mailbox list [-7 | -8] [-A | -u user | -F file | --no-userdb-lookup] [-S socket_path] [-s] [mailbox ...]

Show the status of one or more mailboxes. The mailbox name may also contain wildcards.

This command uses by default the output formatter flow.

-t

guid : The mailbox's globally unique identifier.

highestmodseq : The highest mod-sequence value of all messages in the mailbox.

messages : The number of messages in the mailbox.

recent : The number of messages with the \Recent flag set.

uidnext : The next unique identifier value.

uidvalidity : The unique identifier validity value.

unseen : The message sequence number of the first unseen message in the mailbox.

vsize : The mailbox's virtual size, computed with CRLF line terminators.

firstsaved : Saved time of the first mail in the mailbox.

mailbox subscribe

doveadm [GLOBAL OPTIONS] mailbox subscribe [-A | -u user | -F file | --no-userdb-lookup] [-S socket_path] mailbox ...

This command is used to subscribe one or more mailboxes.

mailbox unsubscribe

doveadm [GLOBAL OPTIONS] mailbox unsubscribe [-A | -u user | -F file | --no-userdb-lookup] [-S socket_path] mailbox ...

This command is used to unsubscribe one or more mailboxes.

mailbox update

doveadm [GLOBAL OPTIONS] mailbox update [-A | -u user | -F file | --no-userdb-lookup] [-S socket_path] [--mailbox-guid guid] [--uid-validity uid] [--min-next-uid uid] [--min-first-recent-uid uid] [--min-highest-modseq seq] [--min-highest-pvt-modseq seq] mailbox ...

This command is used to set UID validity, next UID, first recent UID and modification sequence values.

Usually this is only ever to be used during migration, or restoring mailbox after disaster. Settings these values is highly discouraged, and is not supported for all mail backends.

mailbox cache purge

doveadm [GLOBAL OPTIONS] mailbox cache purge [-A | -u user | -F file | --no-userdb-lookup] [-S socket_path] mailbox ...

Purge the dovecot.index.cache file. Most importantly this frees up disk space from mails that were already deleted. Normally there i no need to run this command manually, because the compression is also run automatically.

mailbox cache decision

doveadm [GLOBAL OPTIONS] mailbox cache decision [-A | -u user | -F file | --no-userdb-lookup] [-S socket_path] [--all] [--fields list of fields] [--last-used unix timestamp] [--decision no|temp|yes] mailbox ...

This command is used to list or change caching decisions for field(s) in mailbox(es). You can list decisions by leaving out decision and last-used parameters.

--all

List or change all fields.

--fields

List or change these comma/space separated fields.

--decision

Set field caching decision. Yes means it's always cached. Temp means it's provisionally cached. No means the field is not cached.

--last-used

Set field's last used timestamp.

NOTE: This command cannot be used to add new fields to cache! You need to first add them to configuration. Setting caching to no will not immediately drop field from cache, it will stop adding the field to cache.

mailbox cache remove

doveadm [GLOBAL OPTIONS] mailbox cache remove [-A | -u user | -F file | --no-userdb-lookup] [-S socket_path] search query

Remove any matching mail(s) from cache.

WARNING! This command can erase ALL cached data, causing system slowness.

See doveadm-search-query(7) for the search query syntax.

EXAMPLE

List subscribed mailboxes, beginning with 'dovecot', of user bob:

doveadm mailbox list -s -u bob dovecot\*

dovecot
dovecot/pigeonhole
dovecot/pigeonhole/2.0

Now have a look at the status of user bob's dovecot mailboxes:

doveadm -f table mailbox status -u bob "messages vsize" dovecot\*

mailbox                                    messages vsize
dovecot                                    20501    93968492
dovecot/pigeonhole                         0        0
dovecot/pigeonhole/2.0                     47       323474

Converting an internationalized mailbox name from mUTF-7 to UTF-8 and vice versa:

doveadm mailbox mutf7 -7 "~peter/mail/&U,BTFw-/&ZeVnLIqe-"

~peter/mail/台北/日本語

doveadm mailbox mutf7 ~peter/mail/台北/日本語

~peter/mail/&U,BTFw-/&ZeVnLIqe-
