What this means for your email list
What this means for addresses at this domain
stanford.edu looks like an organisation's own domain. Those are usually good leads, and also where bounces come from: people change jobs and mailboxes get closed. Checking each address, including whether the server accepts any recipient, avoids damaging your sender reputation.
Sender authentication
stanford.edu uses a DMARC quarantine policy: mail that fails authentication is sent to spam. That is a sound middle step, and a good sign the owner looks after their email setup.
