我尝试了 http://www.google.com/accounts/DisplayUnlockCaptcha 和我可以通过网络浏览器登录到该帐户，而不会出现任何问题.

I have tried http://www.google.com/accounts/DisplayUnlockCaptcha and I can log in to the account through a web browser without any problems.

这发生在我的本地开发机器和公众可访问的站点上.这是我的GMail帐户或我的实施问题吗?

This happens on my local development machine and the publically-accesible site. Is this an issue with my GMail account or my implementation?

推荐答案

您需要允许从不太安全的应用访问，因为通过密码进行的IMAP本质上是不安全的. (不可撤消)

You need to allow access from less-secure apps, because IMAP via password is fundamentally insecure. (it's non-revocable)

更好的是，切换到OAuth身份验证.

Better yet, switch to OAuth authentication.
