如果需要同时运行多个jail，你的rc.conf应该这样配置 {{{ ifconfig_eth0_alias0="inet 10.0.0.179 netmask 255.255.255.255" ifconfig_eth0_alias0="inet 10.0.0.180 netmask 255.255.255.255" jail_enable="YES" jail_list="dns mail" jail_dns_hostname="dns.test.com" jail_dns_ip="10.0.0.179" jail_dns_rootdir="/vhost/jail/179" jail_dns_exec="/bin/sh /etc/rc" jail_dns_devfs_enable="YES" jail_dns_devfs_ruleset="devfsrules_jail" jail_mail_hostname="mail.test.com" jail_mail_ip="10.0.0.180" jail_mail_rootdir="/vhost/jail/180" jail_mail_exec="/bin/sh /etc/rc" jail_mail_devfs_enable="YES" jail_mail_devfs_ruleset="devfsrules_jail" }}} 启动或者停止其中一个jail可以/etc/rc.d/jail start mail或者/etc/rc.d/jail stop dns来操作。 |

qmail下使用python编写脚本来过滤邮件和发送短信
实现qmail下邮件过滤和邮件到达短信通知
作者：梅劲松
时间：2004年9月10日
感谢：HD、刘鑫
短信这么火热，如果自己的邮件服务器也能和短信结合起来，那多么好啊？在qmail下，我用qmail_queue来解决邮件过滤和短信到达通知。
本邮件系统在freebsd 4.10上实施成功。
1. 对于邮件系统的安装，没有太多说的。建议大家看HD的[" http://bsd.huangdong.com/server/mail/qmail.html "]来安装。如果已经安装了有qmail+vpopmail+qmail_queue补丁的，请直接跳到4继续安装。在新装邮件服务器时有几点需要注意的是，安装qmail的时候应该将步骤改为：
cd /usr/ports/mail/qmail make WITH_QMAILQUEUE_PATCH=yes WITH_BIG_TODO_PATCH=yes WITH_OUTGOINGIP_PATCH=yes WITH_PRESERVE_CONFIG_FILES=yes extract cd /usr/ports/mail/qmail/work/qmail-1.03 fetch http://www.nimh.org/dl/qmail-smtpd.c cd /usr/ports/mail/qmail make WITH_QMAILQUEUE_PATCH=yes WITH_BIG_TODO_PATCH=yes WITH_OUTGOINGIP_PATCH=yes WITH_PRESERVE_CONFIG_FILES=yes install make disable-sendmail make enable-qmail make clean
在安装vpopmail的时候可能因为port更新的原因让使用vpopmail的时候出现奇怪问题，最好是安装webmin将建立的vpopmail数据库删除后，重新建立，并指定数据库的用户权限。由于webmin的安装不是本文重点，这里将忽略。
2、关于文章里面的杀毒部分因为系统效率问题，我没有安装。各位请自行决定是否安装。
3、反垃圾邮件当然需要，我用的是[" http://anti-spam.org.cn "]的cbl+服务。使用的时候只需要将smtpd的脚本改为：
QMAILDUID=`/usr/bin/id -u qmaild`
NOFILESGID=`/usr/bin/id -g qmaild`
exec /usr/local/bin/tcpserver -H -R -l 0 -p -x \
/usr/local/vpopmail/etc/tcp.smtp.cdb -u"$QMAILDUID" \
-g"$NOFILESGID" -v -c100 0 smtp rblsmtpd \
-r cblplus.anti-spam.org.cn \
-r relays.ordb.org \
/var/qmail/bin/qmail-smtpd /usr/local/vpopmail/bin/vchkpw-smtpd /usr/bin/true 2>&1从[" http://anti-spam.org.cn/cgi-bin/rblclient/（你的邮件服务器的dns服务器IP地址) "]看到你的邮件服务器的流量和使用cbl+服务的情况。
4、这里是重点了。过滤和短信到达是需要qmail_queue来完成的，一定要打这个包。
使用python来实现这个功能，当然需要安装python啦。
cd /usr/ports/lang/python make;make install;make clean
一般来讲这个安装是非常顺利的。 安装结束后。
