       doveadm-dump - Dump the content of Dovecot's binary mailbox index/log

       doveadm [-Dv] dump [-t type] path

       Dovecot  uses  several binary index and log files in order to improve performance for accessing mails. For some
       mailbox formats, such as sdbox and mdbox, the index files are part of the format  itself.   For  details  about
       index files, see also:

       doveadm  dump  is used to show the contents of those mailbox index/log files, in human readable format. This is
       mainly useful for Dovecot developers when debugging some problem.

       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:

       -t type
              the file type of the file to be dumped.  If the type was omitted, doveadm(1) tries to detect the type of
              path.  type can be:

              dbox        => m.n (sdbox or mdbox mailbox file)

                          Dump the list of expunged mails in dovecot-expunges.log.  Currently used only by fts-lucene.

              index       => dovecot.index,

              log         => dovecot.index.log,

              mailboxlog  => dovecot.mailbox.log

              thread      => dovecot.index.thread

       path   The path to the corresponding dbox storage, index or log  file.   If  only  a  directory  is  specified,
              doveadm tries to detect the type of files under it and dumps them.
