Partial Disposable-domain and role-address checks are easy to vibe-code from public lists, but reliable catch-all detection and deliverability need SMTP probing infrastructure, IP reputation management, and ongoing data maintenance.
What it would actually take: Expose a REST endpoint that runs syntax checks, MX lookups, and a disposable/role domain list, then add SMTP RCPT probing for catch-all detection. The hard parts are sending probes from clean, rotating IPs without getting blacklisted and keeping the disposable-domain data current, which takes ops and deliverability experience.
