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

Overrides the configuration \fIsetting\fR from \fI/etc/dovecot/dovecot.conf\fR and from the userdb with the given \fIvalue\fR. In order to override multiple settings, the \fB-o\fR option may be specified multiple times.

This command uses by default the output formatter \fBflow\fR (without the \fIkey\fR=prefix).
.SH "OPTIONS"
.P
\fB-A\fR
.RS 0
.RS 4
.P
If the \fB-A\fR option is present, the \fIcommand\fR will be performed for all users. Using this option in combination with system users from \fBuserdb { driver = passwd }\fR is not recommended, because it contains also users with a lower UID than the one configured with the \fBfirst_valid_uid\fR setting.
.P
When the SQL userdb module is used, make sure that the \fBuserdb_sql_iterate_query\fR setting setting matches your database layout.
.P
When using the LDAP userdb module, make sure that the \fBuserdb_fields\fR setting and \fBuserdb_ldap_iterate_fields\fR setting settings match your LDAP schema. Otherwise doveadm(1) will be unable to iterate over all users.

\fB-F\fR \fIfile\fR
.RS 0
.RS 4
.P
Execute the \fIcommand\fR for all the users in the \fIfile\fR. This is similar to the \fB-A\fR option, but instead of getting the list of users from the userdb, they are read from the given \fIfile\fR. The \fIfile\fR contains one username per line.
.RE 0

.P
\fB--no-userdb-lookup\fR
.RS 0

Do not perform userdb lookup. Use the \fBUSER\fR environment variable to specify the username.

.P
\fB-S\fR \fIsocket_path\fR
.RS 0
.RS 4
.P
The option's argument is either an absolute path to a local UNIX domain socket, or a hostname and port (\fIhostname\fR:\fIport\fR), in order to connect a remote host via a TCP socket.
.P
This allows an administrator to execute doveadm(1) mail commands through the given socket.

\fBdoveadm\fR \[lB]\fIGLOBAL OPTIONS\fR\[rB] fts optimize \[lB]\fB-u\fR \fIuser\fR | \fB-A\fR | \fB-F\fR \fIfile\fR | \fB--no-userdb-lookup\fR\[rB] \[lB]\fB-S\fR \fIsocket_path\fR\[rB] \[lB]\fInamespace\fR\[rB]
.P
Optimize the full text search index. This is also done automatically by the full text search engines, but this enforces it to happen.
.SS "fts rescan"
.P
\fBdoveadm\fR \[lB]\fIGLOBAL OPTIONS\fR\[rB] fts rescan \[lB]\fB-u\fR \fIuser\fR | \fB-A\fR | \fB-F\fR \fIfile\fR | \fB--no-userdb-lookup\fR\[rB] \[lB]\fB-S\fR \fIsocket_path\fR\[rB] \[lB]\fInamespace\fR\[rB]
.P
Scan what mails exist in the full text search index and compare those to what actually exist in mailboxes. This removes mails from the index that have already been expunged and makes sure that the next \fBdoveadm index\fR will index all the missing mails (if any). Note that currently most FTS drivers do not implement this properly, but instead they delete all the FTS indexes. This may change in the future versions.

.P
Run a simple check on Dovecot Xapian databases, and attempt to fix basic errors (it is the same checking done by the xapian-check command with the \fB-F\fR command-line option).
.P
\fImailbox\fR is the list of mailboxes to process. It is possible to use wildcards (* and ?) in this value.
.P
For each mailbox that has FTS data, it outputs the following key/value fields:
.P
| Key | Value | | --- | ----- | | mailbox | The human-readable mailbox name. (key is hidden) | | guid | The GUID of the mailbox. | | errors | The number of errors reported by the Xapian library. | | shards | The number of index shards processed. |
