qmail的测试问题

Question

我在我的电脑上以安装上了qmail，起动后进行测试得到的结果如下：
[root@clavinduan root]# telnet 127.0.0.1 110
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
Incorrectly built binary which accesses errno, h_errno or _res directly. Needs to be fixed.
+OK <1852.1098841141@clavinduan.com>;
user test
+OK
pass test
-ERR unable to write pipe
Connection closed by foreign host.
[root@clavinduan root]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
我用ps -e |grep qmail查看结果为：
[root@clavinduan root]# ps -e |grep qmail
1845 pts/0    00:00:00 qmail-send
1847 pts/0    00:00:00 qmail-lspawn
1848 pts/0    00:00:00 qmail-rspawn
1849 pts/0    00:00:00 qmail-clean
请问我这里为什么25端口没有打开，还有我的防火墙也关了。
