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.
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.
reconstruct attempts to preserve includes the flag names, flag state, and
Reconstruct derives all other information from the message files.
Reconstruct reads its configuration options out of the
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.
Reconstruct does not adjust the quota usage recorded in any quota
root files. After running
reconstruct, it is advisable to run
-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)
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 mailboxs seen
state unique identifier, user flags, and ACL).
Recursively reconstruct all sub-mailboxes of the mailboxes or mailbox
prefixes given as arguments.
Examine the filesystem underneath mailbox, adding all directories with
a cyrus.header found there as new mailboxes. Useful for
restoring mailboxes from backups.

file. Use whatever data in the existing
mailboxes file it can scavenge, then scans all partitions listed in the
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
reconstruct -r user/ben.lacy
