1、配置postfix邮件服务，首先要停止sendmail服务。
查看sendmail的运行状态，停止运行，并设置为开机不启动。
 
/etc/init.d/sendmail status
/etc/init.d/sendmail stop
chkconfig sendmail off
 
2、安装dns服务
 yum install bind-* -y
配置dns服务
vim /var/named/chroot/etc/named.conf
#####################################
options {
        directory  "/var/named";
};
        zone "liwei.com" {
                type  master;
                file "liwei.com.zone";
        };
编辑正解文件
 vim /var/named/chroot/var/named/liwei.com.zone
#########################################
 $TTL    86400
@               IN SOA  localhost root (

mail.liwei.com.   IN    A       192.168.18.109
liwei.com.        IN    MX 10   mail.liwei.com.
 
重启dns服务
 service named restart
添加启动项

93:myorigin = $mydomain
107:inet_interfaces = all
109:#inet_interfaces = localhost
155:mydestination = $myhostname, $mydomain
255:mynetworks = 192.168.18.0/24, 127.0.0.0/8
287:relay_domains = liwei.com
 
重启服务
