Error coming while starting Postfix !

[AVNISH GUPTA]

Hi Friends
 
I installed Postfix on my RHEL 5 VM and configured it. But I am getting error while starting it.

[root@avnish postfix]# service postfix start
Starting postfix:                                          [FAILED]
[root@avnish postfix]# 


[root@avnish postfix]# postfix check
postfix: fatal: chdir(/usr/libexec/postfix mail_owner = root myhostname = avnish.ericsson.com): No such file or directory

[root@avnish postfix]# 

The directory - /usr/libexec/postfix exists.

[root@avnish ~]# ls -ld /usr/libexec/postfix
drwxr-xr-x 2 root root 4096 Feb  2 11:50 /usr/libexec/postfix
[root@avnish ~]# 

Here are the logs from /var/log/maillog:

[root@avnish ~]# tail -f /var/log/maillog

Here are the settings on my machine:

[root@avnish ~]# hostname
avnish.ericsson.com
[root@avnish ~]# 
[root@avnish ~]# ifconfig | grep inet
          inet addr:147.128.225.92  Bcast:147.128.225.255  Mask:255.255.254.0

147.128.224.160 avnish.niit.com
[root@avnish ~]# 

This error starts coming after I made changes to configuration file - main.cf. I changed few settings in this file like mail_owner, myhostname,  inet_interfaces.

Please let me know how to get rid of this error and getting Postfix started successfully.

Thanks in advance
