What this means for the bank

The checker's own notes on each record:

MX, fail: No MX records, so californiabankofcommerce.com cannot receive mail. Every reply to a cold email sent from it bounces.
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: about 8 of the 10 allowed. One more sending service could push it over. This count is an estimate.
DMARC, fail: No DMARC record at _dmarc.californiabankofcommerce.com. Receivers get no instruction for mail that fails SPF and DKIM, and you get no reports.
DKIM, info: No DKIM key at the 10 common selectors tried. That does not mean DKIM is missing. Your email provider picks the selector name, and DNS has no way to list them.

What this means if you sell to California Bank of Commerce

californiabankofcommerce.com publishes no MX records, so it does not receive mail. California Bank of Commerce's staff mail must run on another domain, which this check did not read. 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.
