[Dovecot] Dovecot quota not working

[Bruno Guimarães Sousa]

Hi everyone,
I'm trying to make quota to work in dovecot 1.0.rc15 in a Debian machine.
Setting the limit to 1GB and starting to fill up the mailbox and nothing
stopped me. It just kept growing and nothing happened.
Restarted the service and nothing.
I had already exceeded the 1 GB limit and nothing happens, the mailbox still
goes bigger and bigger...

The *"check_quota"* plugin for squirrelmail shows "0.0% of 1.0GB" in my
browser. 1GB is exactly what it is defined in dovecot.conf by maildir.

Is it necessary to configure something in postfix?
