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?

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

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。
