发送确认码进行 validate ，当用户确认后即表示存在，
Send a confirmation code to validate , when user confirms that means it exist,
您可以提取电子邮件的域并对该地址进行 ping 操作。如果网络服务器响应“ok”，您就知道电子邮件地址的域是有效的。
尽管在未经发件人确认的情况下，您确实不知道电子邮件是否正确。
问候！
You can extract the domain of the e-mail and make a ping to that address. If the web server response "ok", you know that the domain of e-mail address is valid.
Although you really do not really know if the e-mail is correct without confirmation by the user who writes.
Regards!
