How this service works
DKIM public key for selector "yahoo" of a domain: looks up yahoo._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 yahoo selector will verify. $0.01 per lookup.
Output
Returns parsed DKIM record details for the yahoo._domainkey.<domain> TXT record, including: DKIM version (v=), key type (k=, e.g. rsa), public key length in bits, whether the testing flag (t=y) is present, and whether the key is revoked (empty p= field). Also confirms if mail signed with the yahoo selector will successfully verify.
Example use cases
Pre-send email authentication audit
“Before we start sending marketing emails from acmecorp.com through Yahoo's infrastructure, can you check if the yahoo DKIM selector is properly set up — I need to know the key type, length, and whether it's active or revoked?”
Email deliverability troubleshooting
“Emails from newsletter.io signed with the yahoo selector keep bouncing — can you look up the yahoo DKIM record for newsletter.io and tell me if the key is valid, what type it is, and whether it might be revoked?”
Third-party domain DKIM verification
“We're onboarding a new partner domain partnerco.com that claims to have Yahoo DKIM configured — can you verify their yahoo selector DKIM record and tell me if the public key looks correct and isn't in testing mode?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/yahoo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify the 'yahoo' DKIM selector for a domain, as opposed to other common selectors (microsoft, mx, ms2). Ideal for auditing email authentication configurations for domains that send via Yahoo Mail infrastructure or use Yahoo-branded DKIM selectors. Choose this over generic DNS TXT lookups when you want pre-parsed DKIM field extraction (key type, length, revocation, testing flag) rather than raw DNS output.
Side effects
- Domain has no yahoo._domainkey TXT record — returns not found or empty result
- DNS lookup failure via Cloudflare DoH — network or upstream error
- Malformed TXT record that cannot be parsed — partial or error response
- Revoked key detected (empty p=) — returns revoked status
- Payment not received — 402 response before lookup is performed
