Could you build this?
Partial The API layer, DNS checks, syntax checks, and disposable-domain lists are buildable, but SMTP and catch-all verification at production reliability depends on clean sending IPs, reputation management, and rate-limit handling. Those operational pieces are the hard part.
What it would actually take: A real version would use an async API service with DNS and MX lookups, maintained disposable and role-account lists, and an SMTP probing layer run from a pool of IPs with warm-up and rotation. The hard parts are deliverability and IP reputation management, avoiding blocklisting, and handling greylisting and catch-all ambiguity. This requires email infrastructure and deliverability expertise plus ongoing network operations.
