You (or mail recipients using IMS) can configure IMS to forward messages automatically. This can be useful in a variety of circumstances.
The autoforward feature is set up on a per-user basis, using the IMS.CTL file located in the user's mailbox. You, as administrator, may create and place this file there, or it may be created placed by the user herself.
[AutoForward] ForwardTo = email@example.com [Delivery] Discard = YesThen, any messages (for the user in whose incoming mail directory this file exists) will be forwarded to firstname.lastname@example.org. The Discard entry ensures the message will not be placed in the user's mailbox.
