dovecot - Sep 2009 - Problem with quota in maildir++

Hi all. I have a problem with one user. His quota is upper of real quota.

# cd /var/mail/problemuser/
# find . -name 'dovecot*' -exec rm -f {} \;
# find . -name 'maildir*' -exec rm -f {} \;
# echo test | mail problemuser -s test

# more maildirsize
104857600S
104215602 1439
647 1

# du -h

21M     .

Does anyone know what can happen?
Thanks you.

Well, du -h doesn't necessarily match the quota. For example if the  
user has copied the same message multiple times, du counts its disk  
space only once. I'd guess that's the problem. Perhaps there's a 1
MB
mail that's been copied 80 times or something?

Maybe use something like "ls -l" for each cur/ directory and count the
"total" numbers together. That should give something closer to the  
Maildir++ quota.
