根据需求发送到邮箱service@test.com邮件转发到kf@test.com，并且发送到邮箱kf@test.com也能收到邮件

添加一个本地用户kf

kf:x:2011:2011::/var/spool/postfix/kf:/bin/bash

本地linux系统中有个用户service,为它设置一个别名,是kf

root@linux:mail#vim /etc/aliases

service: kf

还必须编辑/etc/postfix/main.cf文件

alias_maps = hash:/etc/aliases -->用来指定含有用户别名定义的文件路径,alias_database用来指定别名表数据库文件路径.

alias_database = hash:/etc/aliases -->用来指定别名表数据库文件路径.

注意配置文件中等号前后一定要有空格.

修改完配置文件后要使其生效,使用下面的命令

root@linux:mail# postalias /etc/aliases

root@linux:mail# postfix reload

postfix/postfix-script: refreshing the Postfix mail system

postalias命令用来将文件/etc/aliases生成postfix可以读取的数据库文件 /etc/aliases.db

下面我从163邮箱发送邮件到kf@test.com测试

root@linux:mail# pwd
/var/spool/mail
root@linux:mail# tail -f kf
