Validate an email address in two layers: strict RFC-style syntax, then a live DNS MX lookup on the domain to confirm the recipient actually runs mail servers. Catches the typos and fake domains that pure regex misses. Use this when an agent needs to syntax + live MX check — can this address receive mail?.
