check_email_dns
Check email DNS
Use this when the user wants an email DNS check, a DMARC checker, an SPF record checker, a DKIM checker, or an MX lookup for a domain. Reads the live public DNS records through DNS-over-HTTPS and returns MX hosts, the SPF record with its DNS-lookup count against the limit of 10, the DMARC policy, reporting and alignment, DKIM keys for the selectors you give, and a pass/warn/fail findings list with a fix and a CSV report. Do not use for internal DNS server visibility, full deliverability tests, or reading or sending mail.
