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 6 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, pass: Policy p=reject: receivers are asked to refuse mail that fails.
DMARC, warn: pct=80: the policy covers only 80% of mail that fails.
DMARC, info: No rua= address, so you get no reports on what fails.
DKIM, pass: DKIM key found at selector1._domainkey.quill.bank, about 2048-bit RSA.
DKIM, pass: DKIM key found at selector2._domainkey.quill.bank, about 2048-bit RSA.

What this means if you sell to Quill Bank

Quill 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.
