I don't know if i got your question right, but before, while using mbox, we
had less users and much less quota, it was only 200MB now is about 1GB.  And
before we did not have a good backup system, had many problens.
We pretty much change to maildir to be easie to make incremental backups and
etc.

And we are considering testing mbdox or sdbox. But still to earlier to make
another big change like this.
