What this means if you sell to Central Bank

Central 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.
