## Tools (as reported by the server, not verified)

- `check\_domain`: Run every email-authentication check on a domain \(SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT, BIMI, plus domain and mail-server blacklists\) and return a score out of 100, per-check findings and a prioritized fix list. Use this first when asked whether a domain is set up correctly to send email.
- `check\_record`: Look up and validate a single email DNS record for a domain, explaining each tag. record is one of spf, dmarc, dkim, bimi, mta-sts, tls-rpt, mx. SPF counts the 10-lookup limit; DMARC checks policy, reporting and external report authorization; DKIM sizes the key; MTA-STS fetches the policy file and c
- `check\_blacklists`: Check an IPv4 address against about 18 IP blacklists \(SpamCop, Barracuda, UCEPROTECT, PSBL, Mailspike, ...\) or a domain against domain blacklists. Each list is verified with its test entries first, so lists that refuse public resolvers \(such as Spamhaus\) are reported as unavailable rather than clean
- `analyze\_headers`: Parse raw email headers: the Received delivery path with per-hop delays, the receiving server's SPF/DKIM/DMARC verdicts, DMARC alignment of the From domain, DKIM signatures, the sending IP, and bulk-sender requirements such as one-click unsubscribe.
- `check\_spam\_words`: Scan an email subject and body \(plain text or HTML\) for spam-trigger phrases by category, ALL-CAPS, exclamation runs, emoji, URL shorteners and image-heavy HTML. Returns a low/medium/high risk reading and, optionally, a rule-based rewrite.
