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.

fts-lucene Dump the list of indexed mails in lucene-indexes directory

imapzlib Uncompress an IMAP traffic log, which contains data compressed using
the IMAP COMPRESSION extension.

index ⇒ dovecot.index, dovecot.map.index

log ⇒ dovecot.index.log, dovecot.map.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.


Look at the contents of a mailbox's index:

doveadm dump ~/Maildir/.work/
