Easy-to-use security Image

Easy-to-use security

Achieve simple email management with a customizable, at-a-glance dashboard. Multi-tenancy support allows large enterprise and managed service provider deployments with multiple departments or customers to establish organizational units with one or multiple domains. The deployment may be centrally managed, but still allows a given organizational unit to have its own users, sub-administrators, policy rules, junk boxes and more.
