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

Hi!
We do run a debian cyrus 3.0.8-6+deb10u3 mailserver, new setup, but we
did copy over some coonfigs from a older cyrus.
I recently discovered lots of emails in the local storage of the email
server, although the mailbox is empty.
In this case a IMAP shared folder, not a user INBOX.
IMAP tells the folder is empty, but in the folder on the disk still 800
files/mails available, partly 3 month old.
It seems I did miss the automatic removal of mails.
The cyrus.conf shows the line delprune cmd="/usr/sbin/cyrus
expire -E 3"
But it seems I did miss some important point.
On a cyrus restart it shows:
cyrus/cyr_expire[13235]: Expired 0 and expunged 0 out of 1449266
messages from 3993 mailboxes
Anyone has a idea what I did miss, or where to look?
thank you.
MfG,
Lars Schimmer
