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 mailbox.
Cyr_expire
reads its configuration options out of the
imapd.conf(5)
file unless specified otherwise by -C.
OPTIONS
-C config-file
Read configuration options from config-file.
-D delete-days
Remove previously deleted mailboxes older than delete-days
(when using the "delayed" delete mode).
-E expire-days
Prune the duplicate database of entries older than expire-days. This
value is only used for entries which do not have a corresponding
/vendor/cmu/cyrus-imapd/expire mailbox annotation.
-X expunge-days
Expunge previously deleted messages older than expunge-days
(when using the "delayed" expunge mode).
-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.
"user.justgotspammedlots"
-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.
