[Dovecot] Quota not showing properly in webmail

[Eden]

Hi

I have a virtual users system using postfix / mysql / dovecot.

Everything is working like a charm except for the quota display on webmail
systems. It is working properly but showing GB instead of MB.

For example. If I create a user with 100MB of quota and send him 50MB of
mail, squirrelmail and roundcubemail display 50MB of 100GB
If I create another user with 20MB quota and send him 10MB of mail,
squirrelmail and roundcube dipslay 10MB of 20GB. if I send 50MB more I get
the quota error msg I should get. So everything is workign but its
displaying incorrectly. At first I though it was squirrelmail`s fault but it
happens with roundcube as well, since both get their quota info from the
imap server than I think its dovecot.

I`m using Debian 4.0

This is the output of the --version and the -n dovecot commands.
