How this service works
CNAME record of pop3.<domain>: looks up the pop3 host under the domain you give (CNAME via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like pop3 without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the pop3.<domain> CNAME record exists, the record data (target hostname it points to), the TTL value, and the DNS response code. If no CNAME record exists, reports its absence.
Example use cases
Verify email server CNAME setup
“Does pop3.fastmail.com have a CNAME record? I need to know what hostname it points to and whether it's properly configured.”
Audit mail infrastructure for domain
“Can you check whether pop3.acmecorp.com exists as a CNAME in DNS? I'm auditing their email infrastructure and need to know if they have a POP3 endpoint.”
Troubleshoot POP3 connection failure
“My email client can't connect via POP3 to protonmail.com — can you look up whether pop3.protonmail.com has a CNAME record and what TTL it has?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/pop3/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check on whether a specific domain has a POP3 mail host configured as a CNAME, without needing to enumerate all subdomains. Prefer this over general DNS tools when you specifically want the CNAME record type for the pop3 subdomain and want Cloudflare's authoritative DoH response with TTL data.
Side effects
- Domain does not exist — returns NXDOMAIN or empty record set
- No CNAME record at pop3.<domain> — host exists but record type absent
- Cloudflare DoH service unavailable — upstream DNS resolution failure
- Invalid or malformed domain input — request error
- Network timeout on DNS over HTTPS resolution
