通过rails发送的HTML电子邮件以附件的形式到达

以下问题：每当我尝试通过导轨发送HTML电子邮件时，它都以内容为附件的空电子邮件到达我的googlemail-address。通过rails发送的HTML电子邮件以附件的形式到达

我不太确定我在做什么错在这里。

设置如下：

/app/mailers/testmail.rb 
class Testmail < ActionMailer::Base 
    default :from => "[email protected]" 
    default_url_options[:host] = '10.10.8.1' 

    def email 
    subject 'Willkommen!' 
    recipients '[email protected]' 
    from '[email protected]' 
    sent_on Time.now 
    end 
end 

/app/views/testmail/email.html.erb 
<p>Dies ist eine <strong>Testmail!</strong></p> 

/app/views/testmail/email.text.erb 
Dies ist eine Test-Email!

这是我Googlemail电子邮件账户什么到达：

inbox

第一封电子邮件是什么样子与该html.erb和文本.erb激活，第二个只有text.erb。忽略用户名“根”，这是由于后缀重写，因为实际的邮件是另一台服务器上的（从轨服务器的邮件发送给哪个然后实际邮件他们的邮件服务器 - 不是我的设置;）

下面是从第一封电子邮件的原始数据：

好了，找到了答案：组装的电子邮件不包括边界neccessary以上版本。但是，

mail(:to => '[email protected]')

将工作并设置正确的边界。

不知道关于Ruby和或导轨什么，但我知道一点关于MIME。你的顶级Content-Type标题应该是：

Content-Type: multipart/alternative;boundary="--==_mimepart_4e79c96a1adc0_2ba53f7fe85ced90437f9"
