How this service works
DKIM public key for selector "protonmail3" of a domain: looks up protonmail3._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 protonmail3 selector will verify. $0.01 per lookup.
Output
Returns parsed details from the protonmail3._domainkey.<domain> TXT record including: DKIM version (v=), key type (k=), public key material, key length in bits, whether the record is in testing mode (t=y), and whether the key is revoked (empty p= field). Confirms whether email signed with the protonmail3 selector will successfully verify.
Example use cases
ProtonMail DKIM deliverability audit
“Check if example.com has the protonmail3 DKIM selector configured correctly and whether the key is active or revoked — I need to make sure our ProtonMail-sent emails will pass DKIM verification.”
Email security compliance check
“I'm auditing our domain's email authentication setup. Can you look up the protonmail3 DKIM record for mybusiness.com and tell me the key type, length, and whether it's in testing mode?”
Incident investigation after bounce
“We're getting DKIM failures on emails from mycompany.org — can you pull the protonmail3._domainkey TXT record and tell me if the public key is missing or revoked?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/protonmail3?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate or audit the ProtonMail 'protonmail3' DKIM selector for a domain — particularly when verifying ProtonMail email authentication, investigating DKIM-related delivery failures, or performing email security audits. Prefer this over generic DNS TXT lookups when you need structured, pre-parsed DKIM field output (v=, k=, key length, revocation status) rather than a raw TXT string.
Side effects
- Domain has no protonmail3._domainkey TXT record — returns not found or empty result
- DNS resolution failure via Cloudflare DoH — network or upstream error
- Malformed TXT record that cannot be parsed — may return partial or error response
- Revoked key (empty p=) detected and flagged — signals signing will fail
- Rate limiting or payment failure — request rejected before DNS lookup
