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: at least 7 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 dmarcreports@enterprisebank.com.
DKIM, pass: DKIM key found at google._domainkey.enterprisebank.com, about 1024-bit RSA.
DKIM, pass: DKIM key found at s1._domainkey.enterprisebank.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at s2._domainkey.enterprisebank.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at dkim._domainkey.enterprisebank.com, about 2048-bit RSA.

What this means if you sell to Enterprise Bank & Trust

Enterprise Bank & Trust'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.
