Vladas,
While you haven't told us which OS or distribution you're running Cyrus
on, this looks like Debian or Ubuntu, or another distro which follows
the same practice of installing the Cyrus binaries outside of the normal
path, and then uses a wrapper script, /usr/sbin/cyrus, to run those.
In your previous message you included this snippet from your cyrus.conf
file:
deleteprune cmd="/usr/sbin/cyrus expire -E 4 -D 28" at=0430
Here's what that file looks like on my Ubuntu server:
$*file /usr/sbin/cyrus*
/usr/sbin/cyrus: POSIX shell script, ASCII text executable
And this is what running it without an argument will show:
$*/usr/sbin/cyrus*
ERROR: Command cannot be empty
usage: cyrus COMMAND [ARGS]
The most commonly used cyr commands are:
reconstruct reconstruct mailboxes
quota report and optionally fix quota usage
squatter reindex mailboxes
mbpath translate mailbox names to filesystem paths
mboxlist perform operations on the mailbox list database
check perform a consistency check of the cyrus mailstore
tls_prune prune expired sessions from the TLS sessions database
ctl_cyrusdb perform operations common to all Cyrus databases
expire expire messages and duplicate delivery database entries
arbitron arbitron mailboxes
cvt_cyrusdb convert a database file between cyrus database formats
arbitronsort sorts arbitron(8) output
ipurge delete mail from IMAP mailbox or partition based on age or
size
makedirs Sets up the Cyrus IMAPd system directories (spools)
You can get manpages for respective command by prepending cyrus-
prefix to the command name, f.e.:
man 8 cyrus-reconstruct
So on your system you would use "/usr/sbin/cyrus expire" wherever you
see an example using "cyr_expire". In fact the /usr/sbin/cyrus script
is just going to run cyr_expire from the install directory. On my Ubuntu
system that is /usr/lib/cyrus/bin, like so:
$ ls /usr/lib/cyrus/bin/
arbitron ctl_mboxlist cyrdump httpd
makedirs ptdump sivtest
arbitronsort ctl_zoneinfo cyr_expire httptest
master ptexpire smmapd
backupd cvt_cyrusdb cyr_info idled
mbexamine ptloader smtptest
calalarmd cvt_xlist_specialuse cyr_sequence imapd
mbpath quota squatter
chk_cyrus cyr_backup cyr_userseen imtest
mbtool reconstruct synctest
ctl_backups cyr_buildinfo cyr_virusscan installsieve
nntptest restore timsieved
ctl_conversationsdb cyr_dbtool dav_reconstruct ipurge
notifyd sievec tls_prune
ctl_cyrusdb cyr_deny deliver lmtpd
pop3d sieved unexpunge
ctl_deliver cyr_df fud lmtptest
pop3test sieveshell upgrade-db
For Debian/Ubuntu systems this is all explained in
/usr/share/doc/cyrus-common/README.Debian.gz, which includes this paragraph:
The Debian packaging of Cyrus has a few quirks which are important to know
about:
1. Relocation of many Cyrus IMAP files
The default Cyrus install scatters files all over the place. The
Debian package installs only a few files in /usr/bin (cyradm). All
other programs are installed into /usr/lib/cyrus/bin with
convenience tool called /usr/sbin/cyrus which can be used to call
all cyrus utilities. Invoke /usr/sbin/cyrus --help without any
argument to learn more.
If you're going to administer a complex system like Cyrus IMAP, and you
choose to use someone else's packaging, then you need to take some time
to learn the quirks of that packaging.
If you are not using Debian/Ubuntu, then the packages you installed
might be very different from mine, so take the above as only one example
of how this could be done.
The purpose of /usr/sbin/cyrus is twofold. 1) It gives one a single
command, with several sub-commands, to get things done with; and 2) it
ensures that the proper effective UID is used when running those
commands, so as not to corrupt the mailstore or databases. This is very
important, and easy to get wrong otherwise.
Armed with this information, you should be able to figure out how to
expire the expunged messages. Please check out
https://www.cyrusimap.org/ if you have further questions about Expunge.
Cheers,

I am newbie here, although I have installed Cyrus 3.4.3 (and then
upgraded it to 3.4.4) successfully, just thousands of old letters have
already piled up the trash bin yet.
Switching |expunge_mode| from |delayed| to |immediate| in /imapd.conf/
did not start cleaning, and |whereis cyr_expire| finds
//usr/local/cyrus/man/man8/cyr_expire.8.gz/ only — is it not installed
yet? EVENTS{} are left unchanged in /cyrus.conf/:
EVENTS {
# this is required
checkpoint cmd="ctl_cyrusdb -c" period=30
# this is only necessary if using duplicate delivery suppression,
# Sieve or NNTP
delprune cmd="cyr_expire -E 3" at=0400
# Expire data older than 28 days.
deleteprune cmd="cyr_expire -E 4 -D 28" at=0430

# this is only necessary if caching TLS sessions
