Could you build this?
Partial While standard MX lookups and syntax checks are simple, building high-deliverability SMTP handshake verification at scale without getting IP blacklisted requires dedicated infrastructure.
What it would actually take: A production email verification engine requires a distributed pool of warmed IP addresses with proper PTR, SPF, and DKIM setups to perform SMTP handshakes (EHLO/MAIL FROM/RCPT TO) without being immediately greylisted, rate-limited, or blocked by major providers (Google, Microsoft, Yahoo). It also needs heuristics to catch 'catch-all' configurations, disposable email databases, and greylisting retry queues. This necessitates specialized network engineering and IP reputation management.
