1.基本信息
postfix提供smtp协议用来投递邮件
默认端口25
/var/log/maillog ##服务日志
默认情况下邮件端口只在127.0.0.*上开启
2.配置
发送端：
vim /etc/postfix/main.cf ##编辑配置文件
76 myhostname = westos-mail.westos.com ##指定mta主机名称
83 mydomain = westos.com ##指定mta的域名
99 myorigin = $mydomain ##指定邮件来源结尾（@后面的字符内容）
116 inet_interfaces = all ##25端口开启的网络接口
164 mydestination = $myhostname, $mydomain, localhost ##接收邮件结尾字符的指定
systemctl restart postfix.service ##重启服务
systemctl stop firewalld ##关闭防火墙
systemctl disable firewalld ##开机不自启
接受端：
vim /etc/postfix/main.cf ##编辑配置文件
76 myhostname = qq-mail.qq.com ##指定mta主机名称
83 mydomain = qq.com ##指定mta的域名
99 myorigin = $mydomain ##指定邮件来源结尾（@后面的字符内容）
116 inet_interfaces = all ##25端口开启的网络接口
164 mydestination = $myhostname, $mydomain, localhost ##接收邮件结尾字符的指定
systemctl restart postfix.service ##重启服务
systemctl stop firewalld ##关闭防火墙
systemctl disable firewalld ##开机不自启
3.测试
发送端：
mail root@qq.com ##向qq.com发送邮件
Subject: hello ##标题
linux ##内容
. ##用'.'来结束录入内容并发送此邮件
EOT
mailq ##查看邮件队列
Mail queue is empty ##邮件队列为空，表示邮件已发送
postqueue -f ##重新处理邮件队列
postsuper -d id ##删除邮件
mail ##查看邮件
4.邮件别名
接收端：
vim /etc/aliases
别名： 真名 ##邮件别名
admin: root
别名： :include:filename ##邮件群发
moreuser: :include:/etc/postfix/moreuser
user1
user2
systemctl restart postfix.service ##重启服务
发送端
mail 别名@域名
mail admin@qq.com ##向admin发邮件
mail moreuser@qq.com ##群发邮件
mail ##查看邮件，admin的邮件由root接收
mail -u student ##查看student的邮件
5.通过远程主机测试邮件服务
在真机中
yum install telnet -y ##安装telnet
mail from:root@westos.com ##发送端
rcpt to:root@qq.com ##接收端
data
输入邮件内容
quit ##退出
接收端
