邮件收发系统

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

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
77
82 #
83 mydomain = westos.com

98 #myorigin = $myhostname
99 myorigin = $mydomain
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

在mailwestos.westos.com上设置
群发邮件
vim /etc/postfix/users //群发邮件的目标用户配置文件
student
root

vim /etc/aliases
95 # Person who should get root's mail
96 #root: marc
97 admin: root //admin为root的别名
98 more: :include:/etc/postfix/users //群发用户的配置文件
postalias /etc/aliases //更新设置
systemctl restart postfix.service
mail more@westos.com



在maiwestos.com查看邮件
mail -u student
mail -u root //查看root用户收到的邮件



postsuper -d //删除未发送的邮件队列

空壳邮件客户端配置
（1）收件地址伪装
vim /etc/postfix/virtual
# Yorktown Heights, NY 10598, USA
#
admin@qq.com root@westos.com
@qq.com @westos.com //将westos.com 伪装为qq.com
#VIRTUAL(5)
vim /etc/named.rfc1912.zones //添加qq.com这个域
----------------------------------
zone "qq.com" IN {
32 type master;
33 file "qq.com.zone";
34 allow-update { none; };
35 };

dns A 172.25.254.146
qq.com. MX 1 172.25.254.246.
-------------------------------------
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
在 westos.com 上查看是否接受到邮件
mail
& 1 //查看详细信息

（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
从westos主机向linux发送邮件
mail root@linux.com
在linux上查看
mail
& 1 //查看那mail的详细信息
从linux回送邮件到westos
mail admin@westos.com
在westos上查看mail详细信息

telnet
yum install telnet -y
telnet 172.25.254.246 25
ehlo hello //打招呼，查看是否连接成功
mail from:root@qq.com
250 2.1.0 ok

create user postfix@localhost identified by 'postfix';
grant insert,select on email.* to postfix@localhost;
