       cyrreconstruct - reconstruct mailboxes


       cyrreconstruct [ -C config-file ] [ -p partition ] [ -x ] [ -r ] [ -f ]
       cyrreconstruct [ -C config-file ] -m


       cyrreconstruct 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 cyrreconstruct 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  cyrreconstruct  attempts  to  preserve
       includes  the flag names, flag state, and internaldate.  cyrreconstruct
       derives all other information from the message files.

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

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


       -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.

              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.


       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
