If you prefer to use a Cornell email address instead of a third-party email vendor’s sending address, follow the procedure below to establish a Cornell subdomain for sending out email.
A subdomain is an additional section added to a Cornell email domain to identify it, such as “myorg.cornell.edu” or “myorg.mail.cornell.edu”. When a subdomain is created and properly setup through internet identification systems, such as the Domain Name System (DNS), your email will be identified as legitimate by your recipients’ email servers.
