How to change mailbx size on a postfix install on Etch with Virt users

I did a Postfix install on Etch using virtual users and I want to have a large email box. I tried to set a 5G quota limit on an email account but it keeps defaulting back to 2G (2147483647). I tried to change the quota limit in the mysql table as well, but it also keeps defaulting back to 2147483647. Is there a way to set this to a higher limit?
Thanks.

 

Change the type of the quota field in the database from int to bigint.

 

quota limited to 2G

I've tried that but it is not working.
If I set up a quota larger than 2G my email client (IMAP) does not show quota at all, like the account has no quota set.
My system is something like this http://www.howtoforge.com/virtual_users_and_domains_with_postfix_debian_etch

 

Have you tried this with another IMAP client as well? Are there any errors in the mail log?

 

I haven't tried another IMAP client.
I've search on Google and I've found this (this is the behaviour in my case, I've tried to change manually the maildirsize file and this is what happens)

Ok, then the only workaround is to use an x86_64 system instead of i386.
