🟢check_email_dns(domain, dkim_selectors)
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.

}🟢lookup_dns_records(domain, types)
Use this when the user wants a dns lookup, an mx record check, or a txt record lookup for a domain. Reads live public DNS records through DNS-over-HTTPS and returns A, AAAA, MX, NS, TXT, CNAME, CAA, and SOA records with their TTLs, plus a CSV report. Do not use for internal DNS server visibility, reverse DNS of an IP address, or records outside the supported type list.
