NAME
       reconstruct - reconstruct mailboxes

SYNOPSIS
       reconstruct [ -C config-file ] [ -p partition ] [ -x ] [ -r ] [ -f ]
		   [ -k ] [ -s ] [ -g ] [ -G ] mailbox...
       reconstruct [ -C config-file ] -m

DESCRIPTION
       Reconstruct  rebuilds  one or more IMAP mailboxes.  When invoked with the -m switch, it rebuilds the master mailboxes file.  It can be used
       to recover from almost any sort of data corruption.

       If Reconstruct can find existing header and index files, it attempts to preserve any data in them that is not derivable	from  the  message
       files  themselves.   The state reconstruct attempts to preserve includes the flag names, flag state, and internaldate.  Reconstruct derives
       all other information from the message files.

       Reconstruct reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.  Any mailbox  directory  under-
       neath the path specified in the partition-news configuration option is assumed to be in news format.

       Reconstruct  does  not adjust the quota usage recorded in any quota root files.	After running reconstruct, it is advisable to run quota(8)
       with the -f switch in order to fix the quota root files.

OPTIONS
       -C config-file
	      Read configuration options from config-file.

       -p partition
	      Search for the listed (non-existant) mailboxes on the indicated partition.  Create the mailboxes in  the	database  in  addition	to
	      reconstructing them.  (not compatible with the use of wildcards)

       -x     When  processing	a  mailbox  which  is not in the mailbox list (e.g. via the -p or -f options), do not import the metadata from the
	      mailbox, instead create it anew (this specifically affects at least the mailbox's seen state  unique  identifier,  user  flags,  and
	      ACL).

       -r     Recursively reconstruct all sub-mailboxes of the mailboxes or mailbox prefixes given as arguments.

       -f     Examine  the  filesystem	underneath  mailbox,  adding all directories with a cyrus.header found there as new mailboxes.	Useful for
	      restoring mailboxes from backups.

       -k     Preserve the cyrus.expunge file and the corresponding message files instead of deleting them.

       -s     Adds synchronization records to the log, so the synchronization service can replicate the changes.

       -g     Clear existing or regenerated GUIDs for all messages.

       -G     Force regeneration of GUIDs for all messages.

       -m     NOTE: CURRENTLY UNAVAILABLE
	      Rebuild the mailboxes file.  Use whatever data in the existing mailboxes file it can scavenge, then scans all partitions	listed	in
	      the imapd.conf(5) file for additional mailboxes.

EXAMPLES
       You  want  to  reconstruct  the index files for a user, you have recovered a deleted mail file from backup and given it a suitable name (eg
       user/ben-lacy/33.), but it is not visible since it is not indexed:

       reconstruct -r user.ben-lacy

       If you have the unixhierarchysep:yes option set in /etc/imapd.conf you would need to run:

       reconstruct -r user/ben.lacy

FILES
       /etc/imapd.conf
