如何检查给出的电子邮件地址是否存在使用ASP [英] How to check the givem email address exists or not using 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

[e-mail]

te @ hotma.il.com

[e-mail]

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, [e-mail]
[e-mail]
[e-mail]
[e-mail]

推荐答案

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.
