Email Forwarding Rules

The Email Forwarding Rules, often known as Incoming Transport Rules, allow you to define conditions based on which an email can be forwarded. The transport rules will be processed after an email reaches the intended recipient's mailbox. You can configure transport rules in the Incoming Rules section under Security & Compliance.

Note:

  • The Email Forwarding Rules feature will be rolled out in a phased manner and be available only for organizations that use one of our paid plans.
  • If you want the option enabled for your organization, please reach out to us at support@zohomail.com.
