[Dovecot] move the message between folder problem with quota.

Hi, i have dovecot 1.0rc12, postfix, RedHat Enterprise Linux ES 4.0 Update 4. IMAP client Thunderbird 1.5.0.7

Only namespace: namespace private { separator = / inbox = yes prefix = location = maildir:~/Maildir/ }

When the quota limit is near...

more maildirsize 5242880S 0 0 2688058 1 1993336 1

... if i move the message betweeen foders, dovecot say: quota exceeded.

Is this a error?

If i delete the message (trash folder), it not work too.

would not have to work as Maildir++ specification says? http://www.inter7.com/courierimap/README.maildirquota.html (Reading from a Maildir++)

Thanks a lot.
