安装Dovecot 软件包（POP3 和IMAP）
到这里sendmail 服务器基本配置完成后,Mail Server 就可以完成邮件发送工作，如果需要使用
POP3 和IMAP 协议接收邮件还需要安装dovecot 软件包。在rhel5 里dovecot 整合了IMAP。
安装dovecot
软件包要解决其依赖性，安装perl-DBI-1.52-2.el5.i386.rpm、mysql-5.0.77-3.el5.i386.rpm和
dovecot-1.0.7-7.el5.i386.rpm

启动Sendmail 服务
service sendmail restart 和service dovecot restart 命令启动sendmail
和dovecot 服务,
[root@localhost CentOS]# service sendmail

测试端口
使用netstat 命令测试是否开启SMTP 的25 端口、POP3 的110 端口及IMAP 的143 端口。
[root@localhost CentOS]# netstat -ntla
