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 10 of the 10 allowed. One more sending service could push it over. 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 s1._domainkey.centier.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at s2._domainkey.centier.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at mail._domainkey.centier.com, about 2048-bit RSA.
DKIM, info: 7 of the selector lookups failed, so a key may have been missed.

What this means if you sell to Centier Bank

Centier 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.
