sendmail

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
condition = ${if match{$sender_helo_name}{\\.}{no}{yes}}
accept

check_mail:

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。
