I would recommend upgrading vpopmail and qmailadmin. You'll

The server is quite old and has a tenuous grasp on stability, we cannot have
the server/service go down so we are hesitant to perform software upgrades.
We've got new servers we're moving to that are based on Postfix/Dovecot, but
we're trying to 'gently encourage' users to reduce their disk usage beforehand.
The trouble is the quota reporting is telling them they are not over quota at
all.
Where does qmailadmin pull the quota usage numbers from?
vpopmail
I am getting spotty results from 'vuserinfo', for the high-volume users will
generally report 0% quota usage and rarely 100%. Does vpopmail rely on any sort
of caching or internal db for these values? Could this be due to an integer
overflow with such a large mailbox?
As well, for users under quota usages have been reported differently between
the OS/vpopmail and qmailadmin. Is there any caching taking place in qmailadmin?
Try deleting the maildirsize file in a user's Maildir/ to force vpopmail
to regenerate it. If it works, you could put that in a cron. I've been
doing that for a while myself.
I've made the move to postfix/postfixadmin/mysql/dovecot on a number of
systems and am quite happy. Dovecot can even report quota usage
directly to Thunderbird, which is neat. And there are server side
filters using sieve that don't require ftp or shell access. It's all
very nice and up to date.
