.TP
.BI \-o\  setting = value

.\" --- command specific options --- "/.
.PP
Command specific
.IR options :
.\"-------------------------------------
.TP
.B \-A
If the
.B \-A
option is present, the
.I command
will be performed for all users.
Using this option in combination with system users from
.B userdb { driver = passwd }
is not recommended, because it contains also users with a lower UID than
the one configured with the
.I first_valid_uid
setting.
.sp
When the SQL userdb module is used make sure that the
.I iterate_query
setting in
.I /etc/dovecot/dovecot\-sql.conf.ext
matches your database layout.
When using the LDAP userdb module, make sure that the
.IR iterate_attrs " and " iterate_filter
settings in
.I /etc/dovecot/dovecot-ldap.conf.ext
match your LDAP schema.
Otherwise
.BR doveadm (1)
will be unable to iterate over all users.
.\"-------------------------------------
.TP
.BI \-F\  file
Execute the
.I command
for all the users in the
.IR file .
This is similar to the
.B \-A
option,
but instead of getting the list of users from the userdb,
they are read from the given
.IR file .
The
.I file
contains one username per line.
.\"-------------------------------------
.TP
.BI \-S\  socket_path
The option\(aqs argument is either an absolute path to a local UNIX domain
socket, or a hostname and port
.RI ( hostname : port ),
in order to connect a remote host via a TCP socket.
.sp
This allows an administrator to execute
.BR doveadm (1)
mail commands through the given socket.
.\"-------------------------------------
.TP
.BI \-u\  user/mask
Run the
.I command
only for the given
.IR user .
It\(aqs also possible to use
.RB \(aq * \(aq
and
.RB \(aq ? \(aq
wildcards (e.g. \-u *@example.org).
.br
When neither the
.B \-A
option, nor the
.BI \-F\  file
option, nor the
.BI \-u\  user
was specified, the
.I command
will be executed with the environment of the
currently logged in user.
