Account Plans
Plans are sets of restrictions or limits that can be applied to virtual servers. Each plan specifies disk quotas, limits on the number of domains, users and other objects, allowed features and capabilities. A plan can be selected when creating a virtual server, and can be applied to an existing server at any time.

Plans limit what the owner of a domain they are applied to can do. They have no effect on the master administrator, or on resellers (who have their own separate limits).

Each plan has restrictions of the following types :

Disk quotas
These define the inital quotas for a domain, both overall and for the administration user.

Limits
These set the number of domains, mailboxes, aliases and aliases that the domain owner can create. The limits apply to all sub-servers too.

Allowed features
These control which features the domain owner can enable for existing virtual servers or select for new ones, such as a website, DNS domain or email.

Capabilities
These control what attributes of a virtual server the domain owner can manage, such as mail aliases, databases, scripts and backups.
