Wrong info about mailbox quota in ISPConfig

Hi Till,

we have multiserver setup using this tutorial http://www.howtoforge.com/multiserver-setup-with-dedicated-web-email-dns-and-mysql-database-servers-on-debian-squeeze-with-ispconfig-3

After 1 year of using and some updates of ISP is mailbox quota different from real disk quota... Files .quotausage shows real values and size, but only in ISP are values different.

See attached screenshot: http://data.ntisek.cz/data/mailbox_quota.jpg

For example:

File autoservis/.quotausage

priv/quota/storage 50940763 priv/quota/messages 121

File praha/.quotausage

priv/quota/storage 702080186 priv/quota/messages 3346

Is here any function what can do recalculate quotas in ISP or any other resolution?
