近期收到一家客戶寄來的信，因為他發送IP 每隔一段時間會更換，所以一直被greylisting 第一次被擋下，就算我加了對方domain 到允許清單中，還是10封會有8封信會被擋，他發送的IP會從52.103.192.0/24，52.103.193.0/24， 52.103.194.0/24  一直不斷的隨機更換，請問這個除ㄌ把greylisting 關掉外，還有其他方法嗎?

Re: greylisting problem

把这个客户换掉。。。（kidding）

这种行为模式和 spammer 无异，通常就是被挡掉的。为何他要这样做？

我也是第一次遇到這種客人，我想他應該是透過微軟的託管郵箱發送的，感謝你

Re: greylisting problem

如果是托管的邮箱，使用 /opt/iredapd/tools/spf_to_greylist_whitelists.py 将它的域名添加进去即可。
另外也让你的客户添加 SPF dns 记录。
