Roundcube size of mailbox

[dk1988]

Hi every one.
I have a problem with capacity of mailbox. I have configured a postfix+virtual users+mysql+roundcube.
In postfix i have a size of mailbox unlimited but in roundcube i have 900 mb. I want to resize a space off mailbox but i can't find in roundcube where can i do that. I search in configuration file but don't see that.

Thanks for help

so postfix is your smtp server but what is your imap server? it is that which will control your mailbox quotas

I use Courier but in the /etc/courier/authmysqlrc i have comment:
...
#MYSQL_NAME_FIELD
#MYSQL_QUOTA_FIELD quota
...

In mysql i have set 10 GB but in roundcube i have 900 mb

Roundcube gets the quota info from you IMAP server so its there you need to look.
