postfix邮件服务器问题

我按照ExtMail Solution HOWTO for Linux建造了个MAIL SERVER.但是在telnet localhost 25老不对.
还请大家看看呀!

[root@mail-server ~]# telnet localhost 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused



[root@mail-server ~]# netstat -tpln
