發信的 Client 端若在 Mail Server 的內部, Header 會出現 Private IP 的資訊
如: Received: from [192.168.1.77] (host77 [192.168.1.77])
這樣會有資訊洩露的安全性問題
在 header_checks 加上
/^Received:.*\[(192\.168|172\.(1[6-9]|2[0-9]|3[01])|10)\./ IGNORE就可以隱藏這些資訊
/^Received:.*\[127\.0\.0\.1/ IGNORE
How to Enable TCP/IP Forwarding in Windows XP
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"IPEnableRouter"=dword:00000001
相當於 Linux 下的 sysctl -w net.ipv4.ip_forward=1
(echo 1 > /proc/sys/net/ipv4/ip_forward)
昨天第一次用 Sonicare 音波振動牙刷
效果果然和傳說中一樣好, 刷完用舌頭舔牙齒就可以感覺明顯差別, 這是傳統牙刷無法達到的清潔效果.
