Set Quotas in Domains

You can set a maximum mailbox quota for a domain. The default for the domain mailbox quota is unlimited. The domain quota is the maximum amount of storage that can be used by all mailboxes within the domain.

You can set an aggregate quota as well. The sum of the quotas for all accounts in the domain can exceed the size of the aggregate.

An aggregate quota policy for how to handle messages that are sent or received once the aggregate quota has been reached can be set up. The policy options include:

Continue to allow messages to be sent and received as usual

Do not allow messages to be sent

Do not allow messages to be sent or received.

Notifications can be automatically sent when the quota is within a configured percentage of the aggregate quota. A cron tab job runs daily to check the aggregate quota percentage and if the percentage has been reached, the quota warning email is sent.

Note:

When a domain quota is set, the effective quota for an account is the minimum quota setting of either the domain or account.

To configure domain quotas, go to the administration console’s Configure>Domains, domain Advanced page.
