What this means for your email list

Is a free-provider address a problem?

No: plenty of genuine customers use internode.on.net. For business-to-business sales a free address can mean a personal contact instead of a work one, so segment these separately if that matters to you. The address itself still needs checking for typos and dead mailboxes.

Sender authentication

internode.on.net has no DMARC policy, so receivers have no instruction on what to do with mail that fails authentication. Large mailbox providers now expect bulk senders to publish one.
