Enabling e-mail normalization by default

Background In the past, Discourse has shipped with e-mail normalization off. As a result of this, users can create multiple accounts using the same canonical e-mail, through the use of plus addressing. For example, a user with an account tied to bob@discourse.org is able to create another account tied to bob+again@discourse.org. Discourse comes with the normalize_emails site setting which can be flipped to either allow or disallow this. When turned on, it considers both e-mails above to be the …

您检查过 normalize_emails 设置了吗？我并不是说这里没有 bug

[Richie (Richie Rich)]

不，我没有检查过那个设置，我不知道它存在，谢谢 @Canapin

如果这是问题的原因，那么就需要捕获并处理 Internal Server Error 错误，以告知用户为什么不能使用该电子邮件地址。

[sam (Sam Saffron)]

在接下来的四周内，有人将对此进行审查，我们应该向用户显示明确的警告，而不是“内部服务器错误”。

[Richie (Richie Rich)]

谢谢 @sam

此问题已通过此提交修复：

FIX: ensure old email set correctly when updating email (#32309)

如果您有未确认的电子邮件更改，我建议您先在用户偏好设置页面（例如 /my/preferences/account）中将其删除，方法是点击未确认电子邮件旁边的扳手图标，然后点击“删除电子邮件”。

之后，您可以再次开始更改电子邮件的过程，希望这次能正常工作。
