关于MDaemon-20070824-SPF--发件人-ID的日志分析。我有些不理解。

例如 ：

Fri 2007-08-24 00:12:27: Performing SPF lookup (sohu.com / 219.236.3.221)-查找sohu的ＳＰＦ记录
Fri 2007-08-24 00:12:27: *  Policy: v=spf1 ip4:61.135.130.0/23 ip4:61.135.132.0/23 ip4:61.135.134.0/23 ip4:61.135.145.0/23 ip4:61.135.150.0/23 ip4:220.181.26.0/24 ip4:222.28.152.128/25 ip4:218.206.87.0/25 ip4:221.236.12.128 ip4:203.184.141.0/24 ip4:61.152.234.0/24 ~all－在搜狐ＤＮＳ中找到相关ＳＰＦ记录（就是ＳＯＨＵ设置的外发服务器列表）
Fri 2007-08-24 00:12:27: *  Result: softfail－判断对方是冒名的ＳＯＨＵ，不在ＳＰＦ中的ＩＰ.

注意~all和-all的不同，一个返回softfail,一个返回fail.

ＳＰＦ作用：如果对方域名设置了ＳＰＦ记录（Ｔｘｔ），则可判别来自对方域名的邮件是否被假冒。
一般ｓｏｈｕ／１２６／１６３都设置了ｓｐｆ．
