.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.
.RE 0

.RE 0

.P
\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

.RE 0

.P
\fB--no-userdb-lookup\fR
.RS 0
.RS 4
.P
Do not perform userdb lookup. Use the \fBUSER\fR environment variable to specify the username.
.RE 0

.RE 0

.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.
.RE 0

.RE 0

.P
\fB-u\fR \fIuser/mask\fR
.RS 0
.RS 4
.P
Run the \fIcommand\fR only for the given \fIuser\fR. It's also possible to use '\fB*\fR' and '\fB?\fR' wildcards (e.g. -u *@example.org).
.RE 0

.RE 0

.SH "ARGUMENTS"
.P
\fImailbox\fR
.RS 0
.RS 4
.P
Is the name of a \fImailbox\fR, as visible to IMAP clients, except in UTF-8 format. The hierarchy separator between a parent and child mailbox is commonly '\fB/\fR' or '\fB.\fR', but this depends on your selected mailbox storage format and namespace configuration. The mailbox names may also require a namespace prefix.
