配置dovecot实现postfix的发送和接收
[root@master ~]# 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 [root@master ~]# 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
[root@master ~]# 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
[root@master ~]# service dovecot restart

Starting Dovecot Imap: [ OK ]
创建用户测试
[root@master ~]# useradd xueji [root@master ~]# echo "xueji:123456" | chpasswd #以下是三种发送邮件的方式
[xueji@master ~]$ 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） [xueji@master ~]$ echo "aa################bb" | mail -s "sishen" [email protected] < /etc/passwd [xueji@master ~]$ 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
