CentOS - Mar 2009 - Limiting maildir sizes with Postfix?

I have a small Squirrelmail server, using Postfix & Dovecot. I am
trying to limit the amount of mail a user can get. The
"mailbox_size_limit" value does not seem to be being honored. I am
using the Maildir directory format.
>From googling, it appears that "mailbox_size_limit" applies to a
single file (mbox format?), and that it does not work with Maildirs.
Is this correct?

How should I limit the Mailbox size of the users?

I'm not very familiar with Linux "quotas", but I think that is my
only
other choice.

That is a good option, if you happen to be using Courier for your
IMAP/POP3 this option exists as well:

I have no experience with it myself(though I do use Courier in
some places, just without quotas).
