所有电子邮件提供商是否忽略@之前的时段？ [英] Do all email providers ignore periods in front of @?

问题描述

我知道gmail允许用户在@符号之前在电子邮件地址中插入多个句点。 Gmail还允许用户附加如下的电子邮件地址：[e-mail]。所有这些不同的电子邮件地址基本上是相同的地址。 （链接到描述这些功能的Google博客）

I know that gmail lets a user insert as many periods as he/she wants in an email address before the @ sign. Gmail also lets users append the email address like this: [e-mail]. All those "different" email addresses are essentially the same address. (Link to google blog describing these "features")

我想阻止用户使用基本相同的电子邮件地址创建多个帐户。我决定将电子邮件地址存储在我的数据库中，这些时间段和以下内容包括一个+ sing stripped，但现在我想知道：是否忽略电子邮件提供商大多关注的@符号前面的时间段的标准？ p>

I want to prevent users from creating multiple accounts with what is essentially the same email address. I decided to store email addresses in my database with those periods and anything following and including a + sing stripped, but now I am wondering: Is it a standard to ignore periods in front of the @ sign that email providers are mostly following?

推荐答案

这是Gmail特有的，但这适用于域的谷歌应用，所以你只能做到对于@ gmail.com

This is really specific to gmail, but this applies to google apps for domain as well, so you would only be able to do it for @gmail.com

我不会这样做，这只会疏远您的诚实用户，而不会阻止任何人决定创建多个帐户。

I wouldn't do this, this is only going to alienate your honest users and not prevent anyone determined to create multiple accounts.
