Ruby on rails 4 尽管有成功通知，但在heroku生产环境中未收到电子邮件

当我在本地主机上运行“rails s”并发送电子邮件时，我会收到一个通知“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。一切都好

但当我将此部署到heroku并发送电子邮件时，我收到一个通知，“您的姓名已通过电子邮件发送”，但从未收到发送到我真正收件箱的电子邮件。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上进行了现场测试，在注册用户时，我通过同一个应用程序收到了发送到我真实收件箱的电子邮件，因此我相信配置设置是正确的

这简直让我发疯！感谢您的帮助：D

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',

    :enable_starttls_auto => true
  }

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

用户控制器：

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

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

模型/用户：

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

…所以…结果证明我在我的开发环境中没有正确地发送它！：电子邮件说它已经发送了，并且在终端中“发送了”，但是它没有像应该的那样传递目的地变量-因此它没有有效的地方发送电子邮件。（终端将其传递为“目的地”，而不是“目的地”）example@example.com“我没有好好检查一下）。我修正了视图以正确地传递变量，瞧

我重新设置了heroku并手动测试了它-因此我创建了一个新用户，向我的gmail帐户发送了一封激活电子邮件：D。然后我尝试发送第二封电子邮件，它再次通知我该电子邮件已发送，但我的gmail中未出现任何电子邮件：（看起来它可能与config.default\u url选项有关，请删除主机变量并将其设置为config.action\u mailer.default\u url\u options={:host=>'smtp.sendgrid.net'}嘿，我尝试了这一更改并将其推送到heroku-当我从个人资料页面发送电子邮件时，仍然没有收到发送到我gmail的电子邮件。激活用户电子邮件仍然发送（当用户注册时），但此更改断开了该电子邮件中包含的激活链接，该链接将用户发送回网站并激活他们的帐户（好的，那么回到你原来的代码。那么你真的在收件箱中收到了注册电子邮件吗？嘿，是的，已经收到了那部分。注册电子邮件又开始工作了。仍然不知道第二封电子邮件是什么-仍然说已经发过电子邮件，但我的收件箱中没有收到。谢谢主持人的建议！
