Hi!
After searching for hours now, I give up and have to ask here. I try
to use the expire plugin but it always tries to expire my mails
instead of the mails of the user.
I read about the "Mail location setting problem (v1.1-v1.2) and
configured a "mail" extra field in the userdb, but that doesn't have
the effect I want.
I have not idea, what I could try out more, so I ask here.
My setup is the following:

With the following dovecot-sql.conf:
driver = mysql
connect = host=localhost dbname=cyrus user=cyrus password=XXXX
default_pass_scheme = CRYPT
password_query = \
SELECT username, password, concat('*:storage=', quota) AS userdb_quota_rule, '/var/mailstore/%2Mn/%n' as userdb_home, 'maildir:/var/mailstore/%2Mn/%n/mail' as userdb_mail \
FROM passwd WHERE username='%n'
user_query = \
SELECT concat('*:storage=', quota) AS quota_rule, '/var/mailstore/%2Mn/%n' as home, 'maildir:/var/mailstore/%2Mn/%n/mail' as mail \
FROM passwd WHERE username='%n'
And this is dovecot-dict-expire.conf:
connect = host=localhost dbname=dovecot user=dovecot password=XXXXXX
map {
pattern = shared/expire/$user/$mailbox
table = expires
value_field = expire_stamp
fields {
username = $user
mailbox = $mailbox
}
}
In user test's Trash folder there are mails that are older than 1 day
and in dovecot.expires there is
+----------+---------+--------------+
| username | mailbox | expire_stamp |
+----------+---------+--------------+
| test | Trash | 1262779049 |
+----------+---------+--------------+
But if I run
/usr/local/dovecot/sbin/dovecot --exec-mail ext /usr/local/dovecot/libexec/dovecot/expire-tool.sh --test
I get the following output:

As you can see, it uses my username (rrosenfeld) instead of the
username "test", whose mailbox should be expired. But while the above
it printed to the console I get the following in the logfile:
Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] dict: mysql: Connected to localhost (dovecot)
Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth(default): master in: USER 1 test service=internal
Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth(default): prefetch(test): passdb didn't return userdb entries, trying the next userdb
Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth-worker(default): sql(test): SELECT concat('*:storage=', quota) AS quota_rule, '/var/mailstore/09/test' as home, 'maildir:/var/mailstore/09/test/mail' as mail FROM passwd WHERE username='test'
Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth-worker(default): mysql: Connected to localhost (cyrus)
Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth(default): master out: USER 1 test quota_rule=*:storage=10000 home=/var/mailstore/09/test mail=maildir:/var/mailstore/09/test/mail
As you can see, the auth engine sees the request for the user "test".
It also returns the correct home and mail attributes (the above
messages were triggered by my expire call!).
I tried out to comment out the mail_location from dovecot.conf to make
sure that the mail attribute from userdb is used, but this has the
effect, that dovecot expire does not know any mail location setting at
all and tries some "home" directories and different mail storage
formats while my setting mail=maildir:/var/mailstore/09/test/mail from
the userdb is completely ignored:

As you can see, expire tries to access different (default?) mailbox
typies instead of simply using maildir:/var/mailstore/09/test/mail as
defined in the userdb.
So my main problem seems to be, that the mail attribute from the
userdb is completely ignored in expire calls. But how do I fix this?
Tschoeeee
