I decided to see the permission on the files under /etc/mail and this is the output:

Code:
[root@techx mail]# ls -ltr
total 284
-rwxr-xr-x. 1 root root  1847 Jan 27  2014 virtusertable
-rwxr-xr-x. 1 root root   127 Jan 27  2014 trusted-users
-rwxr-xr-x. 1 root root    92 Jan 27  2014 Makefile
-rwxr-xr-x. 1 root root  2700 Jan 27  2014 make
-rwxr-xr-x. 1 root root   997 Jan 27  2014 mailertable
-rwxr-xr-x. 1 root root   233 Jan 27  2014 domaintable
-rwxr-xr-x. 1 root root   724 Sep 12 18:13 access
-rwxr-xr-x. 1 root root 12288 Sep 12 18:13 access.db
-rwxr-xr-x. 1 root root  1041 Jun  9  2014 submit.mc
.....
.....

On my dev server development_techx this works perfectly fine so i decided to compare the permission of the dev which shows

Code:
[root@development_techx mail]# ls -ltr
total 440
-rwxr-xr-x 1 root root  1847 Jan 27  2014 virtusertable
-rwxr-xr-x 1 root root   127 Jan 27  2014 trusted-users
-rwxr-xr-x 1 root root    92 Jan 27  2014 Makefile
-rwxr-xr-x 1 root root  2700 Jan 27  2014 make
-rwxr-xr-x 1 root root   997 Jan 27  2014 mailertable
-rwxr-xr-x 1 root root    64 Jan 27  2014 local-host-names
-rwxr-xr-x 1 root root   724 Sep 12 18:13 access
-rwxr-xr-x 1 root root 12288 Sep 12 18:13 access.db
-rwxr-xr-x 1 root root  1041 Jun  9  2014 submit.mc
-rwxr-xr-x 1 root root 41680 Jun  9  2014 submit.cf
.....

Do you see the difference ?

The problem with techx server is all the files have permission which hows a (.) a (dot) at the end of the permissions when you fire the ls -ltr command which we do not see on development_techx as you can see below.

wrong vs right

-rwxr-xr-x. 1 root root 724 Sep 12 18:13 access vs -rwxr-xr-x 1 root root 724 Sep 12 18:13 access

I had used chmod -R 755 /etc/mail command for changing permission on both the servers.

So why do i see the difference or the (.) in the end and how can i resolve this difference ?

I think it complains about the files having the x-bits.
Please correct them with
Code:
find /etc/mail -type f -exec chmod 644 {} \;

Regarding the . there might be a different ls alias defined in the shell; try \ls. Actually the dot means an ACL; list them with getfacl.

I frankly did not understand what solution you are proposing to make the techx look same as development_techx

Code:
[root@techx ~]# find /etc/mail -type f -exec chmod 644 {} \;
[root@techx ~]# cd /etc/mail
[root@techx mail]# ls -ltr
total 284
-rwxr-xr-x. 1 root root  1847 Jan 27  2014 virtusertable
-rwxr-xr-x. 1 root root   127 Jan 27  2014 trusted-users
-rwxr-xr-x. 1 root root    92 Jan 27  2014 Makefile
-rwxr-xr-x. 1 root root  2700 Jan 27  2014 make
-rwxr-xr-x. 1 root root   997 Jan 27  2014 mailertable
-rwxr-xr-x. 1 root root   233 Jan 27  2014 domaintable
-rwxr-xr-x. 1 root root  1041 Jun  9  2014 submit.mc
-rwxr-xr-x. 1 root root 12288 Aug 25 19:16 access.db
-rwxr-xr-x. 1 root root   641 Sep 17 06:55 access
-rwxr-xr-x. 1 root root 41680 Jun  9  2014 submit.cf

With the above output how to i fix the problem of making techx look same as development_techx ??

I have posted chmod 644.
How comes you quote me wrongly?
I wanted you to escape an eventual alias, with your options becomes
Code:
\ls -ltr

Your getfacl says rw- for user and r-- for group and other, that is correct, but then the ls should show -rw-r--r--.
