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.
Read configuration options from config-file.
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,
-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.
-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.
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
