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 mes‐
sages (when using the "delayed" expunge mode). The expiration of mes‐
sages is controlled by the /vendor/cmu/cyrus-imapd/expire mailbox anno‐
tation which specifies the age (in days) of messages in the given mail‐
box 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.
Read configuration options from config-file.
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 suf‐
fixes are d (days), h (hours), m (minutes) and s (seconds).
Prune the duplicate database of entries older than expire-dura‐
tion. 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.
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 overload‐
ing your server)
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
