Mailgun 沙盒域无法正常工作

Question

Net::SMTPFatalError (554 Sandbox subdomains are for test purposes only. Please add your own domain or add the address to authorized recipients in domain settings.

我在 RoR 应用程序中使用带有 Heroku 的 Mailgun 插件。我正在尝试使用沙盒域，并将我的个人 gmail 帐户添加为授权用户。我正在使用可确认的设计，因此当新用户注册时，应将默认电子邮件发送到他们提供的电子邮件。如下图所示，用户创建成功，并找到了要发送的邮件。 Mailgun 似乎收到了必要的信息，但不相信我已获得授权？

我使用了directions on using Mailgun for Heroku -（复制并粘贴到我的 config/production.rb 中）：

ActionMailer::Base.smtp_settings = {
    :port           => ENV['MAILGUN_SMTP_PORT'],
    :address        => ENV['MAILGUN_SMTP_SERVER'],
    :user_name      => ENV['MAILGUN_SMTP_LOGIN'],
    :password       => ENV['MAILGUN_SMTP_PASSWORD'],
    :domain         => ENV['MAILGUN_DOMAIN'],
    :authentication => :plain,
  }
  ActionMailer::Base.delivery_method = :smtp

我检查了环境变量，它们看起来都是正确的。我还检查了端口 587 是否在 heroku 上使用 telnet。

有什么想法可以从这里开始吗？

mailers/my_mailer.rb 供参考：

class MyMailer < Devise::Mailer   
  helper :application # gives access to all helpers defined within `application_helper`.
  include Devise::Controllers::UrlHelpers # Optional. eg. `confirmation_url`
  default template_path: 'devise/mailer' # to make sure that your mailer uses the devise views

  default from: 'personalemail@gmail.com'
end

Answer 1

我也有这个问题。问题是，在使用 mailgun 沙箱域时，您必须预先注册您的收件人电子邮件才能向其发送电子邮件。为此，请转到您的应用 mailgun 仪表板，单击“授权收件人”，如下图所示。

Where to go to add an authorized recipient

Answer 2

我相信这是 Mailgun 的问题。我确认我有一个与沙盒域关联的授权用户。由于沙盒域没有运气，我注册了一个域，并更新了 Heroku 应用程序设置中的配置变量，并且没有更改上面的代码，收到了电子邮件。

Answer 3

另一种可能性是，如果您输入了自定义域，则您的帐户中有两个域。在这种情况下，更改您在 heroku 上的自定义域的配置变量。
