ruby-on-rails - 发送邮件失败时的 HTTP 状态码

Question

注意:我已阅读 this但我仍然不知道如何正确构建发送电子邮件功能，所以我问这个问题。我需要知道电子邮件发送成功/失败时要使用的 HTTP 状态代码，或者如果这不是正确的做法，那就是正确的做法。

对我的 Rails 应用程序的 POST 请求将发送一封电子邮件。

如果电子邮件发送失败，我应该在 JSON 响应中向发送 POST 请求的人返回什么 HTTP 状态码？

  def inform
    delivered = true
    begin
      UserMailer.new_comment(current_user, other_user, @note).deliver_now
    rescue Net::SMTPAuthenticationError, Net::SMTPServerBusy, Net::SMTPSyntaxError, Net::SMTPFatalError, Net::SMTPUnknownError
      delivered = false
    end

    if delivered
      # I use :created here because email is created
      render json: { delivered: true }.to_json, status: :created
    else
      # I use :service_unavailable here because email sending failed
      render json: { delivered: false }.to_json, status: :service_unavailable
    end
  end
