    Description

      According to RFC 5321 and 5322, mailboxes at top level domain names are permitted. Thus, the syntax localpart@tld is valid. Explicit text to this topic can be found in RFC 5321:

      2.3.5. Domain Names

      A domain name (or often just a "domain") consists of one or more
      components, separated by dots if more than one appears. In the case
      of a top-level domain used by itself in an email address, a single
      string is used without any dots.

      Accordingly, the code

      EmailValidator ev = EmailValidator.getInstance();
      System.out.println(ev.isValid("m@de"));

      should output "true".
