Cyrus 3.0.8 and purging/removing emails

[Savvas Karagiannidis]

Hi,
according to the documentation for cyr_expire (
https://www.cyrusimap.org/imap/reference/manpages/systemcommands/cyr_expire.html)
you also have to add -X parameter in order to completely delete messages
from mailboxes and -D parameter in order to remove deleted mailboxes from
the server. -E is only for expiring old entries in the duplicate messages
databases. Note that the parameter "3" specified there is in days by
default (3d).

So, if you only want to keep data that was deleted the last, let's say, 7
days, and delete anything older than that, you enter the following in the
EVENTS section of cyrus.conf:

delprune        cmd="/usr/sbin/cyrus/cyr_expire -E 3d -X 7d -D 7d" at 0400

The path to cyr_expire is not clear in your email, so please adjust it
accordingly.
"at 0400" specifies that the command must be executed daily at 04:00, you
can of course change it.

Regards,
Savvas Karagiannidis
