Domain Health is InboxPlease's authentication monitor. It resolves the DNS records mailbox providers use to decide whether to trust your email — SPF, DKIM, DMARC and MX — evaluates them against published standards, and reports each finding with the record it came from. Scans re-run on a schedule and every result is kept in the domain's scan history.
