[Dovecot] Problem with Quotas

Hi,

I am using dovecot 1.0.10 and using passwd-file as userdb. I have enabled quota plugin in /etc/dovecot.conf. Extra fields are added into userdb.

user1:X:500:500:User1:/home/user1:/bin/bash:userdb_quota=maildir:storage=1024

Location of the inbox is /var/spool/mail/user1

I dont think this is working. The user already have 5MB in INBOX and if I send a new mail, it is being delivered.

Do I need to change any settings?

Thanks,

Ranjith
