How this service works
DKIM public key for selector "mte2" of a domain: looks up mte2._domainkey.<domain> (TXT, Cloudflare DoH) and parses v=, k=, key type, public-key length, testing flag and whether the key is revoked (empty p=). Confirms that mail signed with the mte2 selector will verify. $0.01 per lookup.
Output
Returns parsed details from the mte2._domainkey.<domain> TXT record including: the v= version tag, k= key type (e.g. RSA, Ed25519), the public key length in bits, whether the testing flag (t=y) is set, and whether the key is revoked (empty p= field). Also confirms if mail signed with the mte2 selector will successfully verify.
Example use cases
Pre-send email authentication check
“Before we launch this email campaign from sendgrid using the mte2 selector, can you verify that the mte2 DKIM key on our domain acmecorp.com is properly set up, not revoked, and not in testing mode?”
Diagnosing DKIM verification failures
“Emails from newsletter.example.org are failing DKIM verification — can you look up the mte2 selector DKIM record for that domain and tell me the key type, key length, and whether the public key is empty or revoked?”
Auditing DKIM configuration for a client domain
“I need to audit the email authentication setup for clientbrand.io — look up their mte2 DKIM selector and report back the key details including whether it's an RSA or Ed25519 key and if it's currently active.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/mte2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to verify the DKIM configuration for the 'mte2' selector on a domain — for example when troubleshooting email deliverability, auditing email authentication, or confirming a newly deployed DKIM key. It is selector-specific and uses Cloudflare DoH for reliable resolution.
Side effects
- Domain does not have an mte2._domainkey TXT record — returns not found or NXDOMAIN
- DKIM record exists but has an empty p= field — key is revoked, verification will fail
- DNS resolution failure via Cloudflare DoH — network or upstream error
- Malformed TXT record that cannot be parsed into expected DKIM tags
- Payment failure — 402 response if x402 payment is not processed
