TL;DR

This capability reads your Cloudflare-managed DNS zone, checks SPF, DKIM, DMARC, and MX records against email-authentication best practices, and proposes fixes for review — applying only narrowly-scoped, low-risk changes directly, consistent with the nqzai Cloudflare connector's read and light-write scope.

If your email bounces, lands in spam, or you just migrated providers, this is a useful first-pass diagnostic — pair it with your mail provider's tools and a DMARC analyzer for anything beyond a safe, reviewed fix.

Email deliverability depends on a precise set of DNS records: SPF, DKIM, DMARC, and MX. A single misconfiguration can cause your messages to bounce, land in spam folders, or be rejected outright. This capability helps you diagnose those “safe” email DNS issues in a Cloudflare‑managed zone and propose fixes, working through nqzai’s Cloudflare connector.

The “Fix my safe email DNS issues in Cloudflare” capability is a diagnostic (and, for narrowly‑scoped safe changes, remediation) workflow that reads your Cloudflare DNS zone and checks it against email‑authentication best practices. When triggered by a user prompt, the system:

  • Reads the DNS records for the Cloudflare zone(s) connected to your account.
  • Analyzes existing SPF, DKIM, DMARC, and MX records against current best practices (e.g., RFC 7208 for SPF, RFC 7489 for DMARC).
  • Identifies common issues such as missing records, syntax errors, overly permissive SPF qualifiers, missing DKIM selectors, or DMARC policies without a reporting address.
  • Proposes a specific set of DNS changes for you to review, and can apply narrowly‑scoped, low‑risk changes directly where the connector’s permissions allow.

The nqzai Cloudflare connector operates on a read and light‑write basis — it’s built to surface issues and propose or make small, safe adjustments, not to silently rewrite your entire DNS configuration or take actions like generating new cryptographic key material on your behalf.

When to Use It

This capability is most useful in the following scenarios:

  • After migrating email providers. When you switch mail providers, SPF and MX records often need updating. This tool can help spot what’s missing or out of date.
  • When email starts bouncing or landing in spam. If you notice a sudden drop in inbox placement, DNS misconfigurations are a common early suspect. Running this check can surface obvious authentication gaps.
  • When you lack DNS expertise. Non‑specialists can use the automated checks as a starting point to understand what’s wrong before making changes.
  • When you need to review DMARC configuration. The tool can point out a missing rua reporting address or an overly permissive policy, so you can decide how to tighten it.
  • After adding a new domain. New domains are often created with only a basic MX record and no email authentication; this tool helps catch that early.

Where Does It Run

Direct answer: The capability runs as a hosted nqzai workflow that connects to your Cloudflare account through the standard nqzai Cloudflare connector (read and light‑write access). At a high level:

  • Cloudflare DNS. The tool reads your zone’s DNS records through Cloudflare’s API, and can make narrowly‑scoped write changes within the connector’s permitted scope.
  • nqzai platform. The analysis and rule‑checking logic runs inside nqzai, comparing your records against known best practices for SPF, DKIM, DMARC, and MX.
  • Chat / dashboard. You trigger the check with a prompt, and results — including any proposed changes — are shown for your review before anything is applied.

Usage is billed under nqzai’s standard pay‑as‑you‑go, per‑token pricing rather than a fixed subscription tier.

How It Works

Direct answer: The capability follows roughly this workflow:

Step 1: Scan and Inventory

The system reads the DNS records for the target zone and categorizes them by type: TXT (SPF, DKIM, DMARC), MX, CNAME, and A/AAAA.

Step 2: Validate Against Best Practices

The system checks each relevant record against a set of rules based on the relevant RFCs and common email‑deliverability practice. For example:

  • SPF: Should begin with v=spf1, stay within the 10‑lookup limit, and avoid an ambiguous ?all qualifier once a domain’s senders are known — the tool will flag this and suggest tightening to ~all (softfail) or -all (hardfail) once you’ve confirmed all legitimate senders are included.
  • DKIM: Should have a valid public key and a selector that matches your mail provider’s expectations. If a DKIM record looks malformed or incomplete, the tool will flag it — regenerating the underlying key pair is something you do with your mail provider, not something this tool does on your behalf.
  • DMARC: Should have a policy tag (p=none, p=quarantine, or p=reject) and an rua reporting address, with SPF/DKIM alignment. The tool will point out a missing reporting address or a policy that looks looser than intended, and generally suggests moving toward p=quarantine cautiously, after you’ve had time to review reports.
  • MX: Should point to a valid mail‑exchange hostname (not a bare IP) with a corresponding A/AAAA record where required.

Step 3: Generate Proposed Changes

The tool produces a diff of the current records versus the recommended ones, with each change annotated with a reason (e.g., “SPF record is missing an include for your email provider”). Nothing is applied silently — you see the proposed change before it happens.

Step 4: Apply Within Scope, With Review

For narrowly‑scoped, low‑risk changes, the tool can apply the update directly through the Cloudflare connector once you confirm it. Larger or more consequential changes (for example, moving DMARC to p=reject) are flagged as something to review and approve deliberately, rather than applied automatically.

Step 5: Post‑Apply Verification

After a change is applied, the tool can re‑check the zone to confirm the records are now syntactically correct. DNS propagation timing depends on the record’s TTL and is outside the tool’s control.

FAQ

Direct answer: Q: Will this break my existing email? A: The tool is designed to be conservative — it won’t change working MX records or push a p=reject DMARC policy without your explicit review and approval.

Q: How long does it take? A: The scan and diff generation typically take well under a minute for a normal‑sized zone. DNS propagation to the rest of the internet depends on your records’ TTLs, which can range from a few minutes upward.

Q: Can I revert the changes? A: You can revert a DNS record change through your Cloudflare dashboard, since the previous value is visible in your zone’s change history.

Q: Does it support multiple email providers (e.g., a marketing tool alongside your primary mail provider)? A: The tool looks at your existing SPF include statements and MX records to understand which senders are already authorized, and will flag if a known provider looks to be missing from SPF. If you use a sender that isn’t detectable from existing records, you may need to add that include yourself.

Q: What about custom DKIM selectors? A: The tool checks whatever DKIM selector and record you already have configured. If it can’t confidently interpret a non‑standard selector, it will flag that for manual review rather than guess.

Trade‑Offs and Risks

Direct answer: No automated diagnostic tool is perfect. A few limitations to keep in mind:

  • Edge cases with complex policies. Domains using subdomain‑level DMARC policies or SPF records split unusually across multiple TXT records may not be fully handled and may need manual review.
  • Over‑zealous DMARC hardfail. Moving to p=reject before verifying that all legitimate senders have SPF and DKIM alignment can block mail from authorized third‑party services (e.g., CRM or marketing‑automation tools). The tool generally recommends a monitoring period at p=quarantine first.
  • No automatic interpretation of DMARC aggregate reports. The tool can help you add or check rua/ruf addresses, but you (or a dedicated reporting service) still need to interpret the reports that come back.
  • Dependency on Cloudflare DNS. If Cloudflare is only your CDN and not your authoritative DNS provider, this capability won’t apply — you need to be using Cloudflare’s nameservers.
  • Scope of automated writes. Because the connector is read and light‑write only, some fixes will be proposed for you to apply manually (e.g., in your mail provider’s console) rather than pushed automatically.

This capability also does not address TLS‑related email security mechanisms (e.g., MTA‑STS or DANE), since those aren’t DNS authentication records in the SPF/DKIM/DMARC sense — those should be handled separately.

Summary and Takeaway

Direct answer: The “Fix my safe email DNS issues in Cloudflare” capability is a way to surface the most common DNS misconfigurations that hurt email deliverability — missing or malformed SPF, DKIM, and DMARC records — and to apply narrowly‑scoped, low‑risk fixes with your review.

It is not a substitute for ongoing email security maintenance. You should still review DMARC reports periodically, coordinate DKIM key rotation with your mail provider, and confirm new senders are reflected in SPF. Use this tool as a first‑pass diagnostic — especially after migrations or when you notice a drop in inbox placement — and follow up with your mail provider or a dedicated DMARC analyzer for anything beyond a safe, reviewed fix.

Evidence, limits, and reproducible use

Direct answer: Reproducible workflow. Review the proposed DNS change against the live zone, authorize only the precise record change needed, and verify the result after propagation. Keep a rollback record for every sending-domain change.

Limit. A configuration check cannot guarantee inbox placement or override DNS propagation, mailbox-provider policy, or a customer's own domain controls.

For the currently exposed nqzai workflow and connection limits, check the public capabilities inventory before relying on a result.

How we keep this honest

Every response nqzai's agent generates is automatically graded by an independent AI judge for accuracy and whether it invents information it can't back up. As of September 2026: sampled responses averaged a 82% quality score over the trailing 7 days (n=39), and our nightly regression suite — which re-runs the agent against a fixed set of real scenarios — passed at a ~93% rate over the last 14 nights. This is internal automated QA, not an independently audited or third-party benchmark; we publish it as a transparency signal, not a claim of perfection.
