配置两台虚拟机的邮件环境

虚拟机                       

nm-connection-editor

                                      //配置虚拟机1.ip为146虚拟机2.ip为246

更改两台主机名分别为mailwestos.westos.com和maillinux.linux.com

配置yum源

[rhel_dvd]

gpgcheck = 0

enabled = 1

baseurl = http://172.25.254.46/hzy

安装dns服务

yum install bind -y

postfix

yum install postfix -y

mailwestos主机和maillinux主机配置如下:

vim /etc/postfix/main.cf

 75 #myhostname = host.domain.tld

 76 myhostname = mailwestos.westos.com

113 inet_interfaces = all

114 #inet_interfaces = $myhostname

115 #inet_interfaces = $myhostname, localhost

116 #inet_interfaces = localhost

163 #

164 mydestination = $myhostname, $mydomain, localhost

systemctl restart postfix

 

mailwestos.westos.com上设置

postmap /etc/postfix/virtual    //加密/virtual文件

postconf -e "virtual_alias_maps = hash:/etc/postfix/virtual" //使系统读取该加密文件,加密方式为hash加密

systemctl restart postfix.service           

mail admin@qq.com

mailq

westos.com 上查看是否接受到邮件

mail

2)邮件回送方伪装

vim /etc/postfix/generic

root@linux.com    root@qq.com        //将回送方伪装为qq.com

postmap /etc/postfix/generic          //加密generic文件

postconf -e "smtp_generic_maps = hash:/etc/postfix/generic" //使系统读取该加密文件,加密方式为hash加密

systemctl restart postfix.service  //重启

postfix服务

westos主机向linux发送邮件

mail root@linux.com

linux上查看

mail

& 1 //查看那mail的详细信息

linux回送邮件到westos

mail admin@westos.com

westos上查看mail详细信息

 

 

 

telnet

yum install telnet -y

telnet 172.25.254.246 25
