ruby-on-rails - Ruby 邮件程序出现 EOFError

Question

我在我的 Controller 中收到有关此代码的 EOFError(文件结束错误)。出现错误的 block 位于 UserMailer.deliver_message( 我不知道如何解决这个问题的行的末尾，我已经被困了大约 2 个月，有人建议这个网站。请帮忙。

  def contact
      @title= "Contact Us"
      if request.post?
       @message= Message.new(params[:contact])
        if @message.valid?
           UserMailer.deliver_message(
            :message => @message
            )
          flash[:notice] = "Thank you for contacting us"
          redirect_to contact_url
         end
        end
      end

消息文件如下:

<%= @message.name %> has sent feedback or a question:

  Message: <%= @message.body %>

  From: <%= @message.email %>

这是 UserMailer

class UserMailer < ActionMailer::Base

  def message(mail)
    subject    'Feedback/Questions'
    recipients 'Email@email'
    from       'webmaster'
    body        mail
  end
end

好的，这是我得到的错误

也许我遗漏了一些非常愚蠢的东西，但如果有人能回答这个问题，那就太棒了。另外，我的解决方法是什么？

如果 SMTP 服务器关闭，也会发生这种情况。 (我使用名为 Sendgrid 的第 3 方邮件程序，当它完全崩溃时发生过一次)
