What this means for your email list
What this means for addresses at this domain
sjsu.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
sjsu.edu has a strict DMARC policy (reject): mail that fails authentication is refused, which protects its brand from spoofing and means anyone sending as sjsu.edu must have SPF and DKIM set up correctly.
