如何检查给出的电子邮件地址是否存在使用ASP
问题描述：
不在数据库中，请参阅我给出的示例，如果您输入电子邮件地址并单击提交按钮，我们可以检查输入的电子邮件地址是否正确。我不是在谈论关于域名检查的验证。
例子，test @ gmail.com
test@yahoo.com
te @ hotma.il.com
test@rediffmail.com
Not in the database, See I am giving an example, Like if you enter a email address and click on the submit button, we are suppose to check the entered email address is correct or not. I am not talking about the validation its about the domain checking.
example, test@gmail.com
test@yahoo.com
te@hotma.il.com
test@rediffmail.com
答
除了检查格式是否正确之外，您无法验证电子邮件地址。由于有许多不同的提供者，因此无法全部了解它们。
You cannot validate email addresses beyond checking that the format looks correct. And since there are many different providers it is impossible to know them all.
