Example prompt: Can you check whether rallylive.ca has its email hosted by Strato Mail — I need to know the MX records and which ones matched the Strato pattern.

## When to prefer this

Use this endpoint when you specifically need to detect Strato Mail as an email hosting provider for a domain. It is purpose-built for Strato Mail pattern matching via MX record lookup, making it more precise than a generic MX lookup tool. Prefer this for sales intelligence, deliverability audits, and migration workflows targeting Strato Mail users in German-speaking or European markets where Strato is prevalent.

## Known failure modes

- Domain does not exist or has no MX records — returns no match with empty MX list
- Cloudflare DoH lookup failure due to network issues — may return an error or timeout
- Domain MX records are ambiguous or use non-standard Strato patterns not yet covered — may return false negative
- Missing or malformed domain input — returns validation error

## How this service works

## Output

Returns a yes/no answer indicating whether the domain's email is hosted by Strato Mail, along with the full list of MX hosts retrieved from Cloudflare DoH and which specific MX hosts matched Strato Mail's known mail-exchanger patterns.
