How this service works
DKIM public key for selector "mailo" of a domain: looks up mailo._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 mailo selector will verify. $0.01 per lookup.
Output
Returns parsed details from the mailo._domainkey.<domain> TXT record including the DKIM version tag (v=), key type (k=), public key material, key length in bits, whether the testing flag is set, and whether the key is revoked (empty p= field). Confirms if mail signed with the mailo selector is expected to verify successfully.
Example use cases
Verify Mailo email deliverability setup
“We just configured Mailo as our email provider for acmecorp.com — can you check the mailo DKIM selector to confirm the public key is active, not revoked, and what key length it uses?”
Audit domain email authentication records
“I need to audit the email security setup for clientdomain.io — can you check the DKIM mailo selector and tell me whether it's properly configured, in testing mode, or revoked?”
Troubleshoot DKIM signing failures for Mailo
“Emails sent from our Mailo account for startup.co are failing DKIM verification — can you check the mailo._domainkey DNS record and tell me what v=, k=, and p= values are present and whether the key looks valid?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/mailo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify or audit the DKIM configuration for the Mailo email service on a domain. It is narrowly scoped to the 'mailo' selector and provides parsed, structured output including key validity and revocation status. Prefer sibling selector-specific endpoints (postmark, sg, squarespace, etc.) for other email providers, or use a generic DKIM lookup if the selector name is unknown.
Side effects
- Domain has no mailo._domainkey TXT record — returns record-not-found response
- DNS resolution failure via Cloudflare DoH — returns a timeout or upstream error
- Malformed TXT record that cannot be parsed — partial or error response
- Key is revoked (empty p=) — returns revoked status rather than an error
- Invalid domain input — returns a validation error
