Upgrade reset mailbox quotas

[phoenixisp]

I am on RH9 and have upgraded from Reloaded 7.1.6 to Reloaded 7.5.2. This happened on two separate servers. Where before the upgrade all mailboxes were set to domain defaults. After the upgrade they are set on "Enter size" and the size is zero. Is there a quick way to reset all mailboxes on the server to "Domain defauly"?

I really don't feel like resetting them all by hand!

Thanks,

Sonny
