过滤中文主题的垃圾邮件

客户有大量的中文垃圾邮件。所有垃圾邮件都与此类似：

电子邮件没有正文，并且每次的主题都不同。qq.com 也不出现在所有电子邮件中。

我尝试使用 spamassassin 来阻止，但是它做不了什么，所以我决定使用 sieve 将所有包含中文/日文/韩文字符集的电子邮件移动到不同的文件夹中。

这可能吗？

更新

尝试了以下变体，均不起作用。

if body :raw :contains "ubject: =?utf-8?B?" {
    fileinto "Junk";
}

答案1

你应该封锁在https://intodns.com/qq.com

以下是我已阻止的 IP 列表，但您应该时不时地检查一下，因为 IP 会不断更改/添加：

101.226.68.138
14.17.19.139
101.227.169.106 
182.140.167.157
182.140.177.149 
123.151.178.115
125.39.247.247
184.105.206.124
203.205.144.156
87.243.6.138  
87.243.6.136 

MX
184.105.206.32 
184.105.206.30 
184.105.206.31 
184.105.206.86 
184.105.206.85 
184.105.206.82 
103.7.30.40
203.205.176.244
203.205.176.240

他们仍会来，但至少他们会直接进入队列并最终进入垃圾桶。
