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, warn: DNS lookups: about 13, 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, warn: Policy p=none with no rua= address. The record asks receivers to do nothing and sends you no reports.
DKIM, pass: DKIM key found at k1._domainkey.nsbvt.com, about 1024-bit RSA.
DKIM, pass: DKIM key found at s1._domainkey.nsbvt.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at s2._domainkey.nsbvt.com, about 1024-bit RSA.

What this means if you sell to Northfield Savings Bank

Northfield Savings Bank routes inbound mail through Proofpoint, a filtering gateway. Expect strict inbound filtering: a message from a sender whose SPF, DKIM or DMARC fails, or whose domain has little sending history, is unlikely to reach a person. 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.
