What this means for the bank

The checker's own notes on each record:

MX, pass: 2 MX records. 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: about 7 of the 10 allowed. This count is an estimate.
DMARC, pass: Policy p=quarantine: receivers are asked to put mail that fails in spam.
DMARC, warn: sp=none: mail claiming to come from a subdomain of nsbonline.com gets no policy, so the subdomains can be spoofed.
DMARC, info: Reports go to lb414mom0r@rua.powerdmarc.com.
DKIM, pass: DKIM key found at k1._domainkey.nsbonline.com, about 1024-bit RSA.

What this means if you sell to Newtown Savings Bank

Newtown Savings Bank's MX hosts belong to a provider we do not name from host names alone. Assume the inbound server checks SPF, DKIM and DMARC and scores reputation, as every major provider does. 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.
