事实上，这是我的，因为我有上运行的应用程序的的Heroku （所以为什么IP地址为 amazonaws.com ），我直接发送电子邮件，通过Gmail SMTP我的应用程序（我不认为它应该的问题，但具体是，我使用的是 gmail_smtp插件我更新的Rails的3.2 ）。

Indeed, this was me, as I have an app running on Heroku (hence why the IP address is from amazonaws.com), and I send email directly from my app via Gmail SMTP (I don't think it should matter, but specifically, I'm using the gmail_smtp plugin which I updated for Rails 3.2).

有没有办法避免这种警告，还是有办法来白名单已知的IP地址？

推荐答案

简答

在Web浏览器（可能是铬/隐身），登录到您的Gmail帐户（一个通过它你想从您的应用程序发送电子邮件）。

[此外，我是pretty的确认的...]点击页面上的按钮，给我带来了https://accounts.google.com/DisplayUnlockCaptcha - 这看起来是这样的：

[Again, I'm pretty sure...] Clicking the button on that page brought me to https://accounts.google.com/DisplayUnlockCaptcha -- which looks like this:

点击继续把我带到了另一个页面：

Clicking Continue brought me to another page:

在这一点上我刚刚去了我的应用程序，并使其发送电子邮件。

At that point I just went to my app, and made it send an email.

注：我的应用程序一般现场测试电子邮件，我在视图触发＃指数有两个按钮，发送 PUT 请求这些操作：触发＃SEND_EMAIL 和触发＃raise_exception 。这使得管理员去 /触发器和发送电子邮件或引发异常的到如果生产系统上进行测试工作正常，只要能够发送电子邮件有关。通过在任何我的应用程序的电子邮件信息引发一个例外，我 exception_notification 。

Note: for general live-testing of email in my app, I have a view at triggers#index with two buttons that send PUT requests to these actions: triggers#send_email and triggers#raise_exception. This enables an admin to go to /triggers and send an email or raise an exception to test if the production system is working correctly as far as being able to send email is concerned. Raising an exception in any of my apps emails details to me via exception_notification.
