What this means for your email list
What this means for addresses at this domain
The domain accepts mail, but whether a given person's mailbox exists depends on that organisation. Company domains often have staff who left, role mailboxes like info@ and sales@, and sometimes catch-all rules that accept everything. Verify the individual address before you send.
Sender authentication
sun.ac.za 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.
