30 23 * * * dspam /usr/local/dspam/bin/dspam_logrotate -a 30 -d /usr/local/dspam/var/dspam/data
（二）配置 dspam
# vi /usr/local/dspam/etc/dspam.conf （以下只写出修改或增加的部分）
-------------------------------------------------------------------------------------------------------------
Trust dspam
Trust postfix
Preference "spamAction=quarantine"
Preference "signatureLocation=headers" # 'message' or 'headers'
Preference "showFactors=on"
Preference "spamAction=tag"
Preference "spamSubject=**SPAM**"
AllowOverride localStore
MySQLServer /var/lib/mysql/mysql.sock
MySQLUser dspam
MySQLPass 123456
MySQLDb dspam
MySQLCompress true
MySQLUIDInSignature on
#LocalMX 127.0.0.1
ParseToHeaders on
#ChangeModeOnParse on
#ChangeUserOnParse on
ChangeUserOnParse user
ClamAVPort 3310
ClamAVHost 127.0.0.1
ClamAVResponse accept
（三） 配置 postfix
# vi /etc/postfix/master.cf （以下只写出修改或增加的部分）
-------------------------------------------------------------------------------------------------------------
smtp inet n - n - - smtpd
-o content_filter=dspam:
dspam unix - n n - 10 pipe
flags=Rhqu user=dspam argv=/usr/local/dspam/bin/dspam --deliver=innocent --user $user -i -f $sender -- $recipient
spam unix - n n - 10 pipe
flags=Ru user=dspam argv=/usr/local/dspam/bin/dspam --class=spam --source=error --user dspam
notspam unix - n n - 10 pipe
flags=Ru user=dspam argv=/usr/local/dspam/bin/dspam --class=innocent --source=error --user dspam
# vi /etc/postfix/main.cf （以下只写出修改或增加的部分）
transport_maps = hash:/etc/postfix/transport
smtpd_client_restrictions = check_client_access pcre:/etc/postfix/dspam_filter_access
local_recipient_maps = proxy:unix:passwd.byname $transport_maps $alias_maps
dspam_destination_recipient_limit = 1
# vi /etc/postfix/dspam_filter_access （建立新的文件，空格用 tab 键）
/./ FILTER dspam:dspam
# vi /etc/postfix/transport （建立新的文件，空格用 tab 键）
spam@redzone.com.cn spam
notspam@redzone.com.cn notspam
# postmap transport
重新启动 postfix 服务
/etc/rc.d/init.d/postfix restart
（四） 启动 dspam
编写一个 dspam 的启动脚本
# vi /usr/local/bin/dspam_startup
------------------内容如下-------------------------------------------
#!/bin/sh
#
# dspam: Starts dspam in daemon mode
#
# with minimal resources.
# processname: dspam
# pidfile: /var/run/dspam.pid
#
# Source function library.
PATH=/usr/local/sbin:/usr/local/bin:/usr/local/dspam/bin
PATH
start() {
echo -n $"Starting dspam: "
dspam --daemon 2>/dev/null &
}
stop() {
echo -n $"Stopping dspam: "
kill $(sudo cat /var/run/dspam.pid)
}
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
*)
echo $"Usage: $0 {start|stop|restart}"
;;
esac
exit $RETVAL
-------------------------------------------------------------------
# chmod 0755 /usr/local/bin/dspam_startup
# dspam_startup start
# ps aux|grep dspam
root 23054 0.0 0.7 5332 1744 pts/0 S 16:35 0:00 dspam --daemon
root 23059 0.0 0.2 6136 660 pts/0 S+ 16:36 0:00 grep dspam
能看到以上信息，说明 dspam 已经启动成功。
（五） 开始测试 dspam
之前我们在 postfix 目录下建立了个文件 transport，内容是：
spam@redzone.com.cn spam
notspam@redzone.com.cn notspam
因此，我们要在 extmail 中建立上面连个邮箱帐号。
用其他邮箱往 redzone.com.cn 发送一测试邮件，在 extmail 收到邮件后，查看邮件的原始信息，可以看到以下信息，则说明 dspam 已经
正常工作：
