We converted from v.2.0.? to v.3.0.? last year. We accepted the
default settings for delete/expunge. Now we have suspicions that
deleted and expunged email is not actually being deleted from the file
system and the space recovered.
Looking at the man page for cyr_expire I see this:
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. A value
of 0 means that no expiration is to be performed
on that mailbox.
The value of the /vendor/cmu/cyrus-imapd/expire
annotation is inherited by all children of the mailbox
on which it is set, so an entire mailbox tree can be
configured by setting 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.
The annotation can be examined using the info command
of cyradm(8), and modified using the mboxconfig and setinfo
commands of cyradm(8).
The following is a representative user mailbox on our server:
info user/usrname
{user/usrname}:
private:
check: NIL
checkperiod: NIL
comment: NIL
sort: NIL
specialuse: NIL
thread: NIL

sieve: NIL
size: 2105288
squat: NIL
synccrcs: 1325519995 0
uniqueid: 6bcd81f457596d11
Our cyrus.conf file has this:
delprune cmd="cyr_expire -D 180d -E 3d -X 180d" at=0400
My question is: When are message files actually removed from our
server's the file system and the space recovered? Is there a setting
or utility option required to perform this action / accomplish this
result? How does one verify the removal?
