Mail quota not working

[ttvilaplana]

Hello,

I've installed Ispconfig 3.0.4.6 in Debian Squeeze

I'm working on a new server rsynced from old one.

In ispconfig interface I can see a lot of mailbox accounts with 0 kb of "Mailbox Quota".
squirrel works fine and I can see the real usage of the maibox hard disk.

Is strange because not all the mailboxes shows 0Kb in the ispconfig "Mailbox quota".

Looking the ispconfig cron.log I can see a lot of entries like this

du: cannot access `/var/vmail/xxxxxx.com/xxxxxxx': No such file or directory

How can I debug this behavior?

Thanks.
