Status:
Closed
Brief Description:
The email domain CORNELL.EDU will be migrated to use the New Inbound Routers. This is a staged rollout that will occur starting on Monday 2/20/2017.
User Impact:
mail sent to @cornell.edu domains will be routed through our new inbound routers.
Services Affected:
Email and Calendar
Full Description:
A new inbound router will cause a change in how spam is handled at Cornell. Previously, email that was identified as spam was rejected by our servers, and senders received a notification that their email had been rejected. Messages will no longer be rejected; they will be marked as quarantined. Users can access these messages via a new feature called Cornell Email Quarantine, and senders will not know their messages were marked as quarantined. The process consists of a series of updates to the SHA.CORNELL.EDU DNS MX records which will incrementally move their email traffic from the Existing Inbound routers to the New Inbound routers. The full migration will take place over four days. In each stage the traffic will be shifted from the current inbound routers to the new inbound routers.
