修改配置文件实现postfix发送邮件

[[email protected] ~]# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.30.130 master sishen.cn
192.168.30.131 slave
[[email protected] ~]# vim /etc/postfix/main.cf 
mydomain = sishen.cn
mynetworks = 192.168.30.0/24,127.0.0.0/8

重启postfix测试

[[email protected] ~]# service postfix restart 
Shutting down postfix:                                     [  OK  ]
Starting postfix:                                          [  OK  ]

 

 

 

 

 配置dovecot实现postfix的发送和接收

[[email protected] ~]# vim /etc/dovecot/dovecot.conf 
protocols = imap pop3 lmtp  #取消前面的注释
login_trusted_networks = 0.0.0.0    #允许所有网络
login_trusted_networks = 192.168.30.0/24  #允许制定IP,两者选其一

[[email protected] ~]# vim /etc/dovecot/conf.d/10-mail.conf 
mail_location = mbox:~/mail:INBOX=/var/mail/%u #取消前面的注释,指定收件箱位置
mbox_write_locks = fcntl   #默认开启,无需更改
 

修改.bash_profile文件

[[email protected] ~]# vim /etc/skel/.bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
if [ ! -d ~/mail/.imap/INBOX ]; then
    mkdir -p ~/mail/.imap/INBOX
fi

重启服务

[[email protected] ~]# service dovecot restart 
Stopping Dovecot Imap:                                     [  OK  ]
Starting Dovecot Imap:                                     [  OK  ]

 

创建用户测试

[[email protected] ~]# useradd xueji
[[email protected] ~]# echo "xueji:123456" | chpasswd
#以下是三种发送邮件的方式
[[email protected]
~]$ mail -s "【xueji】" [email protected] < /etc/hosts #注意这里最好写成[email protected],因为在实际测试过程中,虽然提示发送邮件成功,但实际上收件箱并没有邮件,可能是因为上述配置文件中写的是IP地址段的问题。(个人感觉) [[email protected] ~]$ echo "aa################bb" | mail -s "sishen" [email protected] < /etc/passwd [[email protected] ~]$ mail -s 'test-01' [email protected] #直接回车 11111111111111 # 输入正文 222222222222222 3333333333333333 # 这里想要结束必须回车换到新一行行首 EOT #然后Ctrl+d
