[Dovecot] Maildir ignore

[Tomas Horacek]

 Hello there.

 I do like Dovecot so far, but ran into problem I cant seem to solve,
maybe someone can point me into right direction please.
 I am running version 1.0.rc15 on CentOS 5 Linux i386 system, ext3 fs.
 The problem is I cant get the maildir: and :ignore to work together.
Here is my SQL query, that includes the Quota field.

# cat /etc/dovecot-sql.conf | grep -i quota
user_query = SELECT maildir AS home, 901 AS uid, 901 AS gid,
CONCAT('maildir:storage=', floor(IF(quota!=0, quota,-1)/1000),
':ignore=Trash') AS quota FROM mailbox WHERE username = '%u' AND active
= '1'

 Even Dovecot agrees it seems correct.

# cat /var/log/maillog | grep kaktus | grep quota\= | tail -n1
Sep 30 23:37:33 XXXXXX dovecot: auth(default): master out: USER      
5      XXX at XXX.cz      home=XXX       uid=901 gid=901
quota=maildir:storage=1024:ignore=Trash

 I hope this is the correct way.
 Looking at IMAP communication with Wireshark, the server seems to
ignore my settings.

118 uid copy 22 Trash\r\n
118 NO Quota exceeded\r\n

 Anyone can help me, please ?
 Thank you in advance.
