八，安装POP3服务
需要安装QPopper
http://www.eudora.com/products/unsupported/qpopper/index.html qpopper4.0.8.tar.gz QPopper的安装配置 QPopper是Unix/Linux环境下的POP3服务器，该软件配合Sendmail使用。其主要功能是实现支持用户通过POP3接收信件。安装和配置Qpopper的主要步骤如下：
1.创建从/usr/mail指向/var/spool/mail/的链接（可以省掉）
[root@email src]# ln -s /var/spool/mail/ /usr/mail
2.解压QPopper软件包
[root@email src]# tar xvfz QPopper4.0.3.tar.gz [root@email src]# cd QPopper4.0.3
3.编译安装QPopper
[root@email QPopper4.0.3]# ./configure [root@email QPopper4.0.3]# make [root@email QPopper4.0.3]# make install
注意：安装时可能需要建立相应个文件夹
# mkdir -p /usr/local/man/man8 ******************* 编译需要GCC yum install gcc (安装GCC) yum install glibc yum install pam-devel （编译工具） yum install pam yum install inetd (安装inetd) *******************
编辑/etc/xinetd.d/popper
service pop3 { disable = no socket_type = stream protocol = tcp wait = no user = root server = /usr/local/sbin/popper server_args = -s port = 110 }
然后重新启动：
# service xinetd restart
查看端口情况
netstat –a （应该看到POP3 SMTP端口正常）
添加用户组：popmail
# groupadd popmail
添加用户
# useradd username -g popmail -s /sbin/nologin # passwd username |
