What this means for the bank

The checker's own notes on each record:

MX, pass: 1 MX record. Replies have somewhere to land. Mail is handled by Microsoft 365.
SPF, pass: One SPF record, ending in -all (fail): mail from a server that is not on the list should be rejected.
SPF, warn: DNS lookups: about 11, over the limit of 10 in RFC 7208. Receivers that count the same way return an error, and SPF fails for any message not matched before the limit. This count is an estimate.
DMARC, pass: Policy p=reject: receivers are asked to refuse mail that fails.
DMARC, info: Reports go to 405e2d6bf1b84908a75e0cb0d9bf9e69@dmarc-reports.cloudflare.net.

What this means if you sell to Deerwood Bank

Deerwood Bank 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.
