第二个没有反解 你的日志有点乱，有些应该和这2封邮件无关的，恰好又垃圾进来吧。

我忘记了对方的反查，这台服务器上做了一个特殊的安全处理，不允许对方反查询，打开就好了，谢谢大家：）

自建的郵件服務器沒有做反向解析(沒條件做)。到寫這個帖子為止沒收到退信。
[ 本帖最后由 stdmis 于 2007-7-25 08:50 编辑 ] 真的佩服!! 真的不错的帖子，学到了不少东西，觉得这种反垃圾邮件方法不错。@
回复 #16 stdmis 的帖子
时间比较长是因为对方服务器连你服务器的验证时间长，50秒应该和带宽有关-或者你也和TDK一样设置了15-30秒的SMTP应答延迟。

另外，估计carrie@parisian.co.uk会疯了，很多人给他发测试邮件;P 既然聊到这儿了，再深挖下，，
那些检查域名和IP对应关系的邮件服务器，通过中继发过去的邮件一般都是拒收，谁有解决办法？
像GMAIL那样替换MAIL FROM?
