The domain quota is calculated based on the number of subdomains. Select an edition according to the number of subdomains.
- Subdomains without subdirectories: All subdomains without subdirectories are counted. For example, mail.abc.com and 250.mail.abc.com are counted as two subdomains.
- Subdomains with subdirectories: Subdomains with subdirectories are not counted. For example, mail.abc.com and mail.abc.com/123 are counted as one subdomain.
