虚拟电子邮件地址检查 [英] Dummy email address checking

问题描述

大家好，

您有多少次注意到发送电子邮件时，并非所有电子邮件地址都存在.您会在收件箱中收到一封电子邮件，指出该邮件未送达.那是因为该帐户不存在.

我想在Webform中实现的事情是，当用户输入电子邮件地址时，应自动检查该电子邮件帐户是否为虚拟帐户.

hello all,

How many times have you noticed that when you send an email, that not all the email address exist. You will get an email in your In-box that the mail was not delivered. That is because that account does not exist.

The thing I would like to implement in my Webform is that when user enters an email address it should automatically be checked whether the email account is a dummy or not.

Is there any solution?

推荐答案

您只能使用正则表达式检查输入的字符串是否为有效的邮件地址:
使用正则表达式的电子邮件地址验证 [

You can only check if the entered string is a valid mail address using regular expressions:

You won''t be able to notice if the email account actually exists until you try to send a mail there.
Why don''t you use the standard verification principle that only registers a new user after he clicked a link in the mail he received from you?
