What this means for the bank

The checker's own notes on each record:

MX, pass: 1 MX record. Replies have somewhere to land.
SPF, pass: One SPF record, ending in ~all (softfail): mail from a server that is not on the list is treated as suspect.
SPF, info: DNS lookups: at least 1 of the 10 allowed. This count is an estimate.
SPF, info: The record uses SPF macros, which only resolve for a real message, so the lookup count is a floor.
DMARC, warn: Policy p=none: receivers are asked to do nothing with mail that fails. Reports are on, so you can see what fails.
DMARC, info: Reports go to dmarc_rua@emaildefense.proofpoint.com.
DKIM, pass: DKIM key found at k1._domainkey.centralbank.com, about 1024-bit RSA.
DKIM, pass: DKIM key found at s1._domainkey.centralbank.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at s2._domainkey.centralbank.com, about 1024-bit RSA.

What this means if you sell to Central Bank & Trust Co.

Central Bank & Trust Co. lists MX hosts under its own domain, so it runs or fronts its own mail servers. What filters sit behind them is not visible from DNS; assume they check SPF, DKIM and DMARC like everyone else, and that a bank-run gateway is at least as strict as a commercial one. 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.
