How this service works
DKIM public key for selector "ms2" of a domain: looks up ms2._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 ms2 selector will verify. $0.01 per lookup.
Output
Returns parsed DKIM record data for the ms2 selector including: DKIM version (v=), key type (k=), public key length in bits, whether the testing flag is set, and whether the key is revoked (empty p= field). Also confirms whether mail signed with the ms2 selector should pass DKIM verification.
Example use cases
Audit email deliverability setup
“We just migrated to a new email provider and I want to confirm that the ms2 DKIM selector on acmecorp.com is properly published, not revoked, and will pass DKIM verification for outbound mail.”
Detect revoked or missing DKIM key
“Can you check if the ms2 DKIM key for newsletter.io has been revoked or has an empty public key? I'm seeing DKIM failures and want to know if the record was accidentally cleared.”
Verify key strength before security audit
“Before our security review, can you look up the ms2 DKIM selector for fintech-startup.com and tell me the public key length and key type so we can confirm we're not using a weak RSA key?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/ms2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate the ms2 DKIM selector for a domain, as opposed to other common selectors (shopify, shopify2, google, etc.). Ideal for automated email security audits, deliverability checks, or post-migration verification workflows where ms2 is the selector used by the sending mail service.
Side effects
- Domain has no ms2._domainkey TXT record — returns not-found or empty result
- DNS resolution failure via Cloudflare DoH — returns error
- Domain is invalid or malformed — returns error
- Key is revoked (empty p=) — returns revoked status, not a failure but indicates mail will not verify
- Payment not provided or insufficient — HTTP 402 response
