The checker's own notes on each record:
Partners Bank of New England receives mail through Microsoft 365, whose Exchange Online Protection checks every inbound message's SPF, DKIM and DMARC and scores the sender's reputation. A clean, warmed sending domain is the minimum; a failed check lands in junk or is dropped. Before you send, run your own domain through the email setup checker and publish a policy with the DMARC record generator. For how a bank buys, see the selling to banks playbook.
