It goes like this:
I'm using mysql, postfix, and roundcube.
My mailbox size was 50MB >> roundcube quota indicator was perfect.
Made my mailbox size 1GB roundcube quota indicator went crazy, it reads 100% all the time, and I keep receiving message normally.
On th other hand, Roundcube works very well for the other parts of it.
I only need to have it read the quota correctly.
