What this means for the bank

The checker's own notes on each record:

MX, pass: 5 MX records. Replies have somewhere to land. Mail is handled by Google Workspace.
SPF, pass: One SPF record, ending in -all (fail): mail from a server that is not on the list should be rejected.
SPF, info: DNS lookups: at least 7 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, info: Reports go to dcnrotr3ub@rua.powerdmarc.com.
DKIM, pass: DKIM key found at google._domainkey.mstreetbank.com, about 1024-bit RSA.
DKIM, pass: DKIM key found at s1._domainkey.mstreetbank.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at s2._domainkey.mstreetbank.com, about 2048-bit RSA.
DKIM, info: 7 of the selector lookups failed, so a key may have been missed.

What this means if you sell to MainStreet Bank

MainStreet Bank receives mail through Google Workspace. Gmail requires SPF or DKIM from every sender and DMARC from bulk senders, and filters on reputation. A clean, warmed sending domain is the minimum. Before you send, run your own domain through the email setup checker and publish a policy with the DMARC record generator.
