Currently, Hudu does not perform SPF or DMARC monitoring for subdomains, it only pulls from the domain. We’d like to request support for subdomain-level monitoring. Ideally, Hudu should: Check the subdomain directly for SPF, DMARC, DKIM, and TXT records. For DMARC, if no subdomain record exists, fallback to the base/root domain’s DMARC record.
