NAME

       doveadm-purge - Remove messages with refcount=0 from mdbox files

SYNOPSIS

       doveadm [-Dv] purge [-S socket_path]
       doveadm [-Dv] purge [-S socket_path] -A
       doveadm [-Dv] purge [-S socket_path] -F file
       doveadm [-Dv] purge [-S socket_path] -u user

DESCRIPTION

       The  doveadm  purge  command  is used to remove all messages with refcount=0 from a user's
       mail storage.  The refcount of a message  is  decreased  to  0  when  the  user  (or  some
       administration utility) has expunged all instances of a message from all mailboxes.

       In  the  first  form, doveadm(1) will perform the purge action for the currently logged in
       user.

       In the second form, the command will be executed for all users.

       In the third form, the command will be executed for all users listed in the given file.

       In the last form, only messages of the given user(s) will be purged.

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -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.

       -v     Enables verbosity, including progress counter.

       Command specific 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 iterate_query setting in
              /etc/dovecot/dovecot-sql.conf.ext matches your database  layout.   When  using  the
              LDAP userdb module, make sure that the iterate_attrs and iterate_filter settings in
              /etc/dovecot/dovecot-ldap.conf.ext 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.

       -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).
              When  neither the -A option, nor the -F file option, nor the -u user was specified,
              the command will be executed with the environment of the currently logged in user.
