Defines what happens to the reseller subscription if the total disk space and traffic usage by the reseller's service subscriptions (own reseller's service subscriptions and those belonging to the reseller's customers) reaches the limit values defined by the reseller plan.
You can also set up sending notifications as soon as usage of disk space or traffic reaches a particular value (the Notify when disk space usage reaches and Notify when traffic usage reaches options), in order to prevent subscriptions from suspension. The notifications will be sent to the users or email addresses specified at Tools & Settings > Notifications: Resource usage limits exceeded by reseller account option.
Note: The overuse policy does not apply to the limits set on size of mailboxes. Therefore, even if you enable overuse, be sure to allocate enough disk space to mailboxes.
Overselling policy
Defines whether a reseller can sell more resources than allocated to them with the plan.
If overselling is allowed, a reseller is governed by actual resource usage instead of initial resource allocation. Overselling is a marketing strategy based on the following scheme: a reseller, who was allotted, for example, ten gigabytes of disk space, allocates five gigabytes of disk space for each of their customers, assuming that none of them will actually use all of their allocated disk space.
Customers
Defines the total number of customer accounts that a reseller can create.
Other Resources
Note: Other resources have the same meaning as the ones defined in the hosting plans and subscriptions. The only difference is that a reseller does not use the provided resources directly, but redistributes them by means of service subscriptions they create for their customers or for hosting their own websites.
