ruby-on-rails - Mailgun 沙盒域不起作用

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，应向他们提供的电子邮件发送默认电子邮件。如下图，成功创建用户，找到要发送的邮件。 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，它们都显示准确。我还检查了端口 587 是否在 heroku 上使用 telnet 工作。

任何想法从这里去哪里？

mailers/my_mailer.rb 供引用:

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

我也有这个问题。问题是，当使用 mailgun 沙盒域时，您必须 预注册您的收件人 电子邮件，以便向其发送电子邮件。为此，请转到您的应用程序 mailgun 仪表板，单击“授权收件人”，如下图所示。
