What this means for the bank

The checker's own notes on each record:

MX, fail: No MX records, so signature.bank cannot receive mail. Every reply to a cold email sent from it bounces.
SPF, pass: One SPF record, ending in -all (fail): mail from a server that is not on the list should be rejected.
SPF, info: DNS lookups: about 0 of the 10 allowed. This count is an estimate.
DMARC, pass: Policy p=reject: receivers are asked to refuse mail that fails.
DMARC, info: Reports go to 9bpoj0fe@ag.dmarcian.com.
DKIM, info: No DKIM key at the 10 common selectors tried. That does not mean DKIM is missing. Your email provider picks the selector name, and DNS has no way to list them.

What this means if you sell to Signature Bank of Arkansas

signature.bank publishes no MX records, so it does not receive mail. Signature Bank of Arkansas's staff mail must run on another domain, which this check did not read. 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.
