Partial Syntax, MX, and disposable-domain checks are easy to build. Accurate mailbox verification and high-volume deliverability depend on SMTP probing infrastructure, IP reputation, and curated data lists that take time and scale to build.
What it would actually take: An API service with syntax checks, DNS/MX lookups, SMTP handshake verification, and a disposable-domain database, all behind a fast endpoint. The hard parts are maintaining clean IP reputation so providers don't block probes, and keeping accuracy high against a constantly changing data set.
