不用 anti-spam.org.cn 的 RBL 了…
剛剛發現 anti-spam.org.cn 的 CBL 把 Xuite 的 smtp server 列進去了(IP 是 210.242.46.140)。
所以在 sendmail、Postfix、exim 的設定中把 anti-spam.org.cn 的 RBL 拿掉了。
另外,在 exim 中,把 前一篇 post 的 ACL 擴充成以下這樣:
check_hello:
deny message = HELO/EHLO with wrong IP address.
hosts = !+relay_hosts
log_message = HELO/EHLO my.ip
condition = ${if eq {$sender_helo_name}{###.###.###.###} {yes}{no}}
deny message = HELO/EHLO with wrong IP address.
hosts = !+relay_hosts
log_message = HELO/EHLO localhost
condition = ${if match {$sender_helo_name}{localhost} {yes}{no}}
deny message = HELO/EHLO with wrong IP address.
log_message = HELO/EHLO none
condition = ${if match {$sender_helo_name}{none} {yes}{no}}
deny message = HELO/EHLO with wrong IP address.
log_message = HELO/EHLO no dot

accept
話說… 前一篇 post 的 ACL 加上去之後, reject log 的檔案大小爆跳成原本的三倍多。

不是只有 CPU-Z,GPU-Z 也現身了
以前,CPU 的規格是直接打印在 CPU 上面的,於是有不肖人士將原本打印的時脈更換成更高的時脈,並自行打印上去,藉以賺取差價,這種作法稱為 remark。
隨著軟硬體技術的進步,CPU 內部都被製造廠寫入規格資訊,並能被軟體偵測出來。
在那個時代,大家常常會用 WCPUID 來檢測自己的 CPU 是不是有 remark。
2004 年,WCPUID 的版本維護停止。
後續出現的是 CPU-Z,這套軟體不僅可以偵測 CPU 規格,也一併提供了主機板與記憶體相關資訊。
前陣子,網路上出現了一套新軟體,稱為 GPU-Z,這套軟體可以顯示電腦中的顯示卡相關資訊,舉凡製程、顯示卡匯流排、官方公佈的圖形運算效能、顯卡記憶體規格、顯卡晶片運作時脈、顯卡記憶體運作時脈、…,都能被偵測出來。
我抓下來後,在 PC 跟筆電上面各跑了一遍,截圖如下:
目前,GPU-Z 仍是 beta 版本,編號是 0.1.5。
軟體的檔案大小只有三百多 KB,有興趣的人可以抓下來玩看看。
