What this means for your email list
What this means for addresses at this domain
Mail routing for rit.edu is healthy, so the domain is not the risk. The risk is the mailbox: outdated contacts, shared inboxes and catch-all servers. A mailbox-level check tells you which addresses are safe to send to.
Sender authentication
rit.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.
