尽管收到了成功通知，但在heroku生产环境中没有收到电子邮件

Question

当我在本地主机中运行"rails s"并发送电子邮件时，我收到一个通知，"您的名字已通过电子邮件发送"，并在终端中看到它似乎已经工作了。一切都好！

但当我将其部署到heroku并发送电子邮件时，我收到了一个通知，"你的名字已通过电子邮件发送"，但从未收到我真正收件箱中的电子邮件。你知道我为什么没有收到邮件吗？

我已经为用户身份验证系统设置了电子邮件，并在heroku上进行了实时测试，当我注册用户时，我通过这个应用程序收到了发送到我真实收件箱的电子邮件，所以我相信配置设置是正确的。

这把我逼疯了！感谢任何帮助：D

配置文件控制器：

def email
    @user = User.find(params[:id])
    destination = params[:to]
    name = params[:name]
    user = User.find(params[:id])
    user_mailer = UserMailer.profile(@profile, destination, name, user)
    if user_mailer.deliver
      flash[:success] = "Your name was emailed"
      redirect_to @user
    else
      flash[:danger] = "Your name could not be emailed"
      redirect_to @user
    end
  end

环境/生产：

# Sendgrid config
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.delivery_method = :smtp
  host = 'example.herokuapp.com'
  config.action_mailer.default_url_options = { host: host }
  ActionMailer::Base.smtp_settings = {
    :address        => 'smtp.sendgrid.net',
    :port           => '587',
    :authentication => :plain,
    :user_name      => ENV['SENDGRID_USERNAME'],
    :password       => ENV['SENDGRID_PASSWORD'],
    :domain         => 'heroku.com',
    :enable_starttls_auto => true
  }

如果这有助于以下是一些与用户激活相关的信息，以显示其他电子邮件是如何在应用程序中设置的（当在heroku/gmail上测试时，这些电子邮件在现实生活中有效）

用户控制器：

def create
    @user = User.new(user_params)
    if @user.save
      @user.profile = Profile.new
      @user.send_activation_email
      flash[:info] = "Please check your email to activate your account."
      redirect_to root_url
    else
      render 'new'
    end
  end

模块/用户：

  # Sends activation email.
  def send_activation_email
    UserMailer.account_activation(self).deliver
  end

Answer 1

。。。所以……事实证明，我在开发环境中根本没有正确发送它！：s电子邮件说它已经发送了，并且在终端中"发送"了，但它没有按照应该的方式传递目的地变量，所以它没有有效的发送电子邮件的地方。（终端将其传递给"destination"而不是"[e-mail]我没有好好检查）。我修正了视图以正确地传递变量，瞧！
