Recipient Verification: Ensuring Safe Email Delivery at UNH

March 7, 2017

by UNH IT Staff

In response to increased email phishing, spoofing, and malware campaigns, UNH Information Technology will be enabling Recipient Verification on Wednesday, March 15. This feature reviews in-bound email claiming to be addressed to recipients at UNH, and verifies that the intended addressee exists in our email directory service. Think of it as a passport for email that verifies both sender and recipient to ensure safe delivery.

UNH IT has tested the Recipient Verification service for a year now in an audit mode, and all of the email filtered has been ‘junk’; we have yet to find a single legitimate email identified by this process. Of the 15 million messages UNH receives bi-weekly, only 30,000-50,000 fail recipient verification. Email systems that have been white-listed, or proven to be legitimate, will not be affected by this new service.
