[root@mail ~]# bind-chroot-admin –s
|
|
[root@mail ~]# service named restart
[root@mail ~]# chkconfig named on
|
|
[root@mail ~]# mkdir /media/rhel5
[root@mail ~]# mount /dev/cdrom /media/rhel5
[root@mail ~]# cd /media/rhel5/Server
[root@mail Server]# rpm -ivh createrepo-0.4.4-2.fc6.noarch.rpm
[root@mail Server]# cd /media/
[root@mail media]# createrepo .
[root@mail ~]# vi /etc/yum.repos.d/rhel-debuginfo.repo
修改为以下内容
[rhel5]
baseurl=file:///media
enabled=1
gpgcheck=0

[root@mail ~]# rpm -ivh postfix-2.3.3-2.i386.rpm
|

[root@mail ~]# vi /etc/postfix/main.cf
inet_interfaces = all //设置监听25端口在哪些IP地址可以使用
myhostname = mail.lwb.com //设置Postfix服务器使用的主机名
mydomain = lwb.com //设置Postfix服务器使用的邮件域
myorigin = $mydomain //设置发件人邮件地址中的邮件域名
mydestination = $mydomain,$myhostname //设置可接收的邮件地址中的域名
home_mailbox = Maildir/ //设置邮件存储位置和格式
|
|
[root@mail ~]# service postfix restart
[root@mail ~]# chkconfig postfix on
[root@mail ~]# netstat -antp |grep :25
查看其25端口是否是如下信息（看是否有4个0）
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 4626/master

[root@mail ~]# yum install dovecot* -y

|
|
[root@mail ~]# service dovecot restart
[root@mail ~]# chkconfig dovecot on
查看其端口信息
[root@mail ~]# netstat -anpt |grep dovecot
tcp 0 0 :::110 :::* LISTEN 4687/dovecot
tcp 0 0 :::143 :::* LISTEN 4687/dovecot

[root@mail ~]# service httpd restart
[root@mail ~]# chkconfig httpd on
|
