How this service works
TXT record of webmail.<domain>: looks up the webmail 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 webmail without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the webmail.<domain> subdomain exists in DNS, its TXT record values (if any), the TTL, and the DNS response code (e.g. NOERROR or NXDOMAIN).
Example use cases
Email infrastructure recon for a domain
“I'm auditing the email setup for acme.com — can you check whether webmail.acme.com has any TXT records, and tell me what they say?”
Verifying webmail host existence before migration
“Before we migrate our mail system, can you confirm whether webmail.oldcompany.org exists in DNS by looking up its TXT records?”
Security check for webmail subdomain exposure
“I need to know if webmail.targetdomain.com is a live subdomain with TXT records — can you do a quick DNS lookup and report the results?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/webmail/txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check for the TXT DNS record of the webmail subdomain of a specific domain, without running a full subdomain enumeration. Ideal for email infrastructure audits, domain reconnaissance, or verifying whether a webmail host is configured. Prefer this over general DNS tools when you specifically need TXT records for the webmail host and want Cloudflare DoH resolution.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- webmail subdomain not configured — returns NXDOMAIN or empty records
- Malformed domain input — may return error or empty response
- Cloudflare DoH service unavailable — lookup fails with no result
- TXT record exists but is empty — returns empty record set with NOERROR
