       cyr_expire - expire messages and duplicate delivery database entries

       cyr_expire [ -C config-file ] [ -D delete-days ] -E expire-duration [ -X
       expunge-days ] [ -p  mailbox-prefix ] [ -v ]

       Cyr_expire is used to expire messages and duplicate delivery database
       entries.  Cyr_expire also cleanses mailboxes of partially expunged
       messages (when using the "delayed" expunge mode).  The expiration of
       messages is controlled by the /vendor/cmu/cyrus-imapd/expire mailbox
       annotation which specifies the age (in days) of messages in the given
       mailbox that should be deleted.  Any duplicate delivery database entries
       which correspond to the mailbox are also deleted at the same frequency.

       The value of the /vendor/cmu/cyrus-imapd/expire annotation is inherited
       by all children of the given mailbox, so an entire mailbox tree can be
       expired by seting a single annotation on the root of that tree.  If a
       mailbox does not have a /vendor/cmu/cyrus-imapd/expire annotation set on
       it (or does not inherit one), then no messages are expired from the

       Cyr_expire reads its configuration options out of the imapd.conf(5) file
       unless specified otherwise by -C.

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

       -D delete-duration
              Remove previously deleted mailboxes older than delete-duration
              (when using the "delayed" delete mode).  The value can be a
              floating point number, and may have a suffix to specify the unit
              of time.  If no suffix, the value is number of days.  Valid
              suffixes are d (days), h (hours), m (minutes) and s (seconds).

       -E expire-duration
              Prune the duplicate database of entries older than expire-
              duration.  This value is only used for entries which do not have a
              corresponding /vendor/cmu/cyrus-imapd/expire mailbox annotation.
              Format is the same as delete-duration.

       -X expunge-duration
              Expunge previously deleted messages older than expunge-duration
              (when using the "delayed" expunge mode).  Format is the same as

        -x    Do not expunge messages even if using delayed expunge mode
              (reduces the IO hit considerably, allowing you to run cyr_expire
              frequently to clean up the duplicate database without overloading
              your server)

       -p mailbox-prefix
              Only find mailboxes starting with this prefix.  e.g.

       -v     Enable verbose output.

       -a     Skip the annotation lookup, so all /vendor/cmu/cyrus-imapd/expire
              annotations are ignored entirely.  It behaves as if they were not
              set, so only expire-days is considered for all mailboxes.
