What this means for the bank

The checker's own notes on each record:

MX, pass: 1 MX record. 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.

What this means if you sell to Builtwell Bank

Builtwell Bank lists MX hosts under its own domain, so it runs or fronts its own mail servers. What filters sit behind them is not visible from DNS; assume they check SPF, DKIM and DMARC like everyone else, and that a bank-run gateway is at least as strict as a commercial one. 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.
