How this service works
TXT record of pop3.<domain>: looks up the pop3 host under the domain you give (TXT 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> subdomain exists in DNS, its TXT record values, and the TTL of those records, as resolved by Cloudflare DNS over HTTPS.
Example use cases
Verify pop3 mail host configuration
“Check if pop3.example.com has any TXT records configured in DNS — I want to know if the pop3 subdomain is actually set up for that domain.”
Email infrastructure audit
“I'm auditing the mail setup for acmecorp.com — can you check whether their pop3 subdomain has TXT records in DNS and what those records say?”
Monitor pop3 subdomain presence
“Has the pop3 subdomain for mydomain.net been added to DNS yet? Please check its TXT records and let me know the TTL if it exists.”
