## NAME

**doveadm-rebuild** - Commands related to rebuilding various aspects of mails matching given search query.

## SYNOPSIS

**doveadm** \[*GLOBAL OPTIONS*\] \[**-f** *formatter*\] **rebuild** \<command\> \[**-S** *socket\_path*\] **-A** *search\_query*

**doveadm** \[*GLOBAL OPTIONS*\] \[**-f** *formatter*\] **rebuild** \<command\> \[**-S** *socket\_path*\] **-F** *file* *search\_query*

**doveadm** \[*GLOBAL OPTIONS*\] \[**-f** *formatter*\] **rebuild** \<command\> \[**-S** *socket\_path*\] **--no-userdb-lookup** *search\_query*

**doveadm** \[*GLOBAL OPTIONS*\] \[**-f** *formatter*\] **rebuild** \<command\> \[**-S** *socket\_path*\] **-u** *user* *search\_query*

## DESCRIPTION

The **rebuild attachments** command is used to rebuilds attachment presence. [doveadm(1)](/doveadm/1.md) will print the message's uid for each match.

When used with the **-A** or **-u** *wildcard* options, [doveadm(1)](/doveadm/1.md) will print the fields **username** and **uid** for each matching message.

In the first form, [doveadm(1)](/doveadm/1.md) will execute the **rebuild** action for all users.

In the second form, the command will be performed for all users listed in the given *file*.

In the third form, the command will be performed for the user contained in the *USER* environment variable.

In the last form, only matching mails of the given *user* (s) will be rebuilt

## GLOBAL OPTIONS

Global [doveadm(1)](/doveadm/1.md) *options*:

- **-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 **-o**.

- **-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.

  **json**

  prints a JSON array of JSON objects.

  **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.

This command uses by default the output formatter **flow** (without the *key* = prefix).

## 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)](/doveadm/1.md) 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)](/doveadm/1.md) 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

*search\_query*

Resets attachment indicator for messages matching this search query. See [doveadm-search-query(7)](/doveadm-search-query/7.md) for details.

## EXAMPLE

Rebuild user bob's attachment status:

```
doveadm rebuild attachments -u bob ALL
```

```
1
2
3
```
