I can not believe, you have a singel server with "hundreds of thousands"
mailboxes, because I know some VERY BIG providers which hit the limit
with arround 50-60.000 Mailboxes per physicaly server.

I have a very fast Sun Machine and run into trouble with 20.000 accounts
if they access the mailboxes between 08:00 and 17:00. And of course, I
am using 4 Income-MTA-Proxys which distribute the messages to 86 mailbox
servers.

However, my quotas are in the PostgreSQL database and I can change it
with some clicks in less then 10 seconds.
