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, warn: DNS lookups: about 14, 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, pass: Policy p=quarantine: receivers are asked to put mail that fails in spam.
DMARC, info: Reports go to syslog@ombbank.com.
DKIM, pass: DKIM key found at selector1._domainkey.ombbank.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at k1._domainkey.ombbank.com, about 1024-bit RSA.
DKIM, pass: DKIM key found at s1._domainkey.ombbank.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at s2._domainkey.ombbank.com, about 2048-bit RSA.

What this means if you sell to Omb Bank

Omb Bank'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.
