It's not just TLDs. Machine aliases are also perfectly valid in e-mail addresses, e.g. "root@localhost", "fred@finance" etc. This might not be practical in a majority of applications (you're hardly going to sign up to 3rd party services using an alias to a machine on your local network) but if you're building a generic e-mail address validation library, it's an edge case you cannot ignore. |
