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 (fail): mail from a server that is not on the list should be rejected.
SPF, info: DNS lookups: about 9 of the 10 allowed. One more sending service could push it over. This count is an estimate.
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 aea98a75b7d04734b6d153f5a53d60b1@dmarc-reports.cloudflare.net.
DKIM, pass: DKIM key found at k1._domainkey.amboybank.com, about 1024-bit RSA.
DKIM, pass: DKIM key found at s1._domainkey.amboybank.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at s2._domainkey.amboybank.com, about 1024-bit RSA.

What this means if you sell to Amboy Bank

Amboy Bank routes inbound mail through Mimecast, 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.
