What this means for your email list

Is a free-provider address a problem?

Addresses at telefonica.net are legitimate and deliverable in general. What goes wrong is the mailbox part before the @: typos, old accounts and abandoned inboxes. That is what per-address verification catches.

Sender authentication

telefonica.net has DMARC in monitoring mode (p=none). It collects reports but does not yet block spoofed mail, so the domain is easier to impersonate.
