postfix on VPS

[theboy]

Hi,
I have installed postfix on my vps(centos4.5) .It has plesk that by default
installed qmail. So I remove qmail rpm . Now when I telnet to
[root@vps111 ~]# telnet 127.0.0.1 25
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
220 vps111.dom.com ESMTP Postfix
---its OK

ifconfig

venet0 inet addr:127.0.0.1
venet0:0 inet addr:1.4.4.14
venet0:1 inet addr:1.4.4.15

It does not have any iptable firewall .
[root@vps111 ~]# iptables -nL
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

I can connect to the server through ssh . But I can not telnet to 25 port
of any of those ip(1.4.4.14/15) from inside or outside.
[root@vps111 ~]# telnet 1.4.4.14 25
Trying 1.4.4.14...
telnet: connect to address 1.4.4.14: Connection refused

[root@vps111 ~]# telnet 1.4.4.15 25
Trying 1.4.4.15...
telnet: connect to address 1.4.4.15: Connection refused

Also my /etc/hosts file is also rewritten ... by some old value ?

Can any one suggest what to do ? Please help me.Thanks.

What's the output of

netstat -tap

? What's the value of inet_interfaces in /etc/postfix/main.cf?

Hi,
Thx for reply . The postfix problem is solved . But there is another
problem . My /etc/hosts file is rewritten by a process (I faill to detect ,how?)
I have change the/etc/hosts ...but after reboot it rewritten by old value along with my values . Can you give me idea ...what to do ?

I think this happens because it's a virtual machine. The hosts file is generated from the virtual machine's configuration file (which is on the host system) each time the vm is booted.
