防止垃圾邮件，号召大家整理一个国内 ADSL 的IP分配表出来

　　我简单粗略的分析了一下，目前国内垃圾邮件的来源多半是用一些专用的垃圾邮件群发软件制造出来的，使用的多半是 动态分配IP的 ADSL线路，而国内 ADSL IP 地址的分配多有规律，中国电信的 ADSL 一般多是 218.0.0.0 网段，我简单了试了一下在 tcpserver 中 deny 掉 218. ，则收到的垃圾邮件至少减少了三分之一。如果再配合 spamcontrol 软件过滤信封中 bad 的 HELO MAIL RCPT 等命令，则垃圾邮件至少减少三分之二以上。效果还真不错。

　　不过 218. 中也有些分配作为固定 IP ，这就比较难办了。惟一的办法是通过网络，号召大家来整理一份国内的 ADSL 用户的动态 IP 分配表，我相信只要大家努力，一定能够将垃圾邮件降低到最低程度。

　　以下是我仅仅查看了不过１０封垃圾邮件得到的结果，我会不断地往这个列表中添加，希望得到大家的支持。

天呀，这样一来，我看，连不连网没有意义了，都deny了

立法才是真正的解决办法！IP没多少用的！毕竟有些客户都是用的ADSL，会误杀的！

大麻 回复于：2003-07-19 08:45:19

应该说 badhelo 还是有一定的效果，例如有很多垃圾邮件的 helo 使用了 163.net 163.com ，而正常从 163.net 过来的信件一般是 bjmx1.163.net 之类的完整地址。当然，制作垃圾邮件群发的软件稍稍聪明一点的话，我们也拿他没有办法。

大麻兄试试偶的方法看看？偶的方法对垃圾邮件过滤服务器的要求很低的，偶用PII 350+128M RAM就跑的很快了，看cpu、磁盘IO、postfix队列，很空闲。就算有垃圾能进入垃圾邮件过滤服务器，postfix也会因为dns解析不出而无法发送，对于这种队列，只管删就行了。
