How this service works
CNAME record of imap.<domain>: looks up the imap 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 imap without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the imap.<domain> CNAME record exists, the record's target hostname, TTL value, and any associated DNS record data retrieved via Cloudflare DoH. If the record does not exist, the response indicates absence.
Example use cases
Email client auto-configuration check
“I'm setting up an email client for users of acmecorp.com — can you check whether imap.acmecorp.com has a CNAME record and what host it resolves to?”
Onboarding domain readiness verification
“Before we finish onboarding startup.io to our mail platform, can you confirm that imap.startup.io has a CNAME DNS record configured and show me the TTL?”
Diagnosing IMAP connection failures
“Our users on example.net can't connect to IMAP — can you check if imap.example.net exists as a CNAME record and what it points to?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/imap/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-purpose existence and resolution check for the imap.<domain> CNAME specifically, without enumerating other subdomains. Ideal for email infrastructure validation, onboarding checks, and diagnosing IMAP connectivity issues. Prefer this over general DNS tools when you only care about the imap host and want a pay-per-lookup model with Cloudflare DoH reliability.
Side effects
- Domain does not exist — no records returned
- imap subdomain has no CNAME record (may have A/AAAA instead)
- Malformed domain input causing query failure
- Cloudflare DoH upstream timeout or error
- Rate limiting or payment failure resulting in no response
