Checks whether an email address is well-formed and whether its domain actually has working mail servers, returning the parsed domain, the sorted list of mail hosts, and a deliverable flag. Doesn't probe the specific mailbox, only the domain's mail setup. Built for lead-list cleaning and signup-form validation agents. Nothing is stored.
