Postfix的安装与配置步骤:
安装与配置postfix:
准备软件安装包
[root@localhostdocs]#lspostfix.tar.gz
postfix.tar.gz
解压压缩包
[root@localhostdocs]#tarzxvfpostfix.tar.gz-C/
进入解压路径
[root@localhost/]#cd/postfix/
[root@localhostpostfix]#ls
配yum:
配置yum源,dhcp获取
[root@localhostpostfix]#vim/etc/yum.repos.d/ftp.repo
[base]
name=base
baseurl=ftp:
//192.168.7.249/iso/Server
enabled=1
gpgcheck=0
[postfix]
name=postfix
baseurl=file:
///postfix
1、安装postfix:
[root@localhostpostfix]#yuminstall-ypostfix
2、处理后事:
停掉所有占用25端口的服务。
[root@localhostpostfix]#/etc/init.d/sendmailstop
[root@localhostpostfix]#chkconfigsendmailoff
切换MTA:

配置DNS:
[root@localhostpostfix]#yuminstall-ybindbind-chroot
[root@localhostpostfix]#cd/var/named/chroot/etc/
[root@localhostetc]#ls
localtimerndc.key
编辑配置文件
[root@localhostetc]#vimnamed.conf

测试:
指定dns服务器
[root@localhostnamed]#vim/etc/resolv.conf
[root@localhostnamed]#cat/etc/resolv.conf
searchlocaldomain
nameserver192.168.7.249
测试dns服务器是否解析成功
[root@localhostnamed]#host-tmxextmail.org

配置MTA:
[root@mailnamed]#cd/etc/postfix/
[root@mailpostfix]#ls
配置文件解释
[root@mailpostfix]#lsreadme/#有各种配置文件参数的解释
生成新的配置文件:
[root@mailpostfix]#postconf-n>
