·准备
1.
postfix提供smtp协议用来投递邮件
默认端口25
/var/log/maillog##服务日志
mail [email protected]
Subject: hello
hello world
.#用"."来结束录入内容并发送
mailq##查看邮件队列
postqueue -f##重新处理邮件队列
默认情况下邮件端口只在127.0.0.1上开启
2.
配置
vim /etc/postfix/main.cf
116 inet_interfaces = all##25端口开启的网络接口
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 = westos.com##指定邮件来源结尾（@后面的字符内容）
164 mydestination = $myhostname, $mydomain, localhost##接收邮件结尾字符的指定
systemctl restart postfix.service
systemctl stop firewalld
3.邮件别名
[[email protected] ~]# vim /etc/aliases
别名：真名##邮件别名
别名：:include:filename##邮件群发
vim filename
user1
user2
postalias /etc/aliases
mail 别名
4.通过远程主机测试邮件服务
[[email protected] Desktop]$ telnet 172.25.254.100 25
Trying 172.25.254.100...
Connected to 172.25.254.100.
Escape character is ‘^]‘.

5.邮件客户端的访问控制
#限制客户端
在mta上
postconf -e "smtpd_client_restrictions = check_client_access hash:/etc/postfix/access"
vim /etc/postfix/access
172.25.254.22REJECT
postmap /etc/postfix/access
systemctl restart postfix
测试

##出站地址伪装
postconf -e "smtp_generic_maps = hash:/etc/postfix/generic"
vim /etc/postfix/generic

postmap /etc/postfix/generic
systemctl restart postfix
测试
su - westos
mail [email protected]
##入战地址转换
dns mx 记录解析先做好
postconf -e "virtual_alias_maps = hash:/etc/postfix/virtual"
/etc/postfix/virtual
虚拟名字真实用户
[email protected]@westos.com
postmap /etc/postfix/virtual
systectl restart postfix
测试
