主机和客户端都改为DNS服务端的ip
vim /etc/resolve.conf
nameserver 172.25.254.124
dig -t MX timo.com
dig -t MX rito.com
主客都改，发送接受都改
vim /etc/postfix/main.cf
75 myhostname = mailtimo.timo.com#主机名
83 mydomain = timo.com #域
99 myorigin = $mydomain #邮件后缀域名
113 inet_interfaces = all #开放所有端口
116 #inet_interfaces = localhost #注释掉
164 mydestination = $myhostname, $mydomain, localhost#本机能接受的邮件类型
systemctl restart postfix.server
发送不出去的两个原因：
systemctl stop firewalld.service #关闭防火墙
netstat -antlpe | grep 25 #查看端口是否开放
mail root@rito.com#写邮件
abc
def
.
EOT
mail #查看邮件
mail -u root #查看有关root的邮件
mailq #查看排队邮件
postsuper -d QUEUE-ID #删除排队的邮件
