What this means for your email list

Is a free-provider address a problem?

Not by itself. webmail.co.za is a normal mailbox provider used by real people, and mail to it is delivered reliably. The thing to watch is whether the specific mailbox exists, which a domain check cannot tell you, so verify each address.

Sender authentication

webmail.co.za has a strict DMARC policy (reject): mail that fails authentication is refused, which protects its brand from spoofing and means anyone sending as webmail.co.za must have SPF and DKIM set up correctly.
