From the OIT Help Desk,

Is it possible to have all of my Unity email forwarded to another email
address?

Yes, you can have your incoming email forwarded to any other email address.
Mail forwarding is handled via the self-service forwarding mechanism at:
https://sysnews.ncsu.edu/tools-bin/usmdb-forwards

As per the ruling of the University Information Technology Committee (UITC) as
of 8 March 2006, mail forwarded to off-campus email addresses will be screened
for spam. Any messages marked as spam by the campus mail relays will NOT be
forwarded to the off-campus address.

Please note that email forwarding is an all-or-nothing situation. If your Unity
email is being forwarded to another location, it will not be possible to
continue to read the email in the Unity system.

For more information on mail forwarding, please see:

If you are experiencing any other problem, please call the Help Desk at
919-515-4357 and we will trouble shoot for you over the phone. Our hours are
7am-6pm Monday-Friday (closed on weekends and Hollidays).
