Hi Barney,

   Here I just wanted to explain you that what exactly I am trying to do is,

1] I am trying to configure postfix mail server that can only send mails.
It receives no mail from the network.

2] The MX records tell the world which server will accept inbound mail for
your domain. They have nothing to do with sending outbound mail. That's
why I have not made any DNS entry for my domain "textwand.com".

3] Locally generated mails will be forward ALERT / INFO /CRITICAL
notifications generated by my local syslogd to me. I want generated log
reports to go to my "manoj.burandeartificialmachines.com" account.

4] I have hosted my JAVA application on the same server. And it will
generate mail to deliver to the users. e.g. mmburandegmail.com /
yahoo.com or manoj.burandeartificialmachines.com etc..In short it will
deliver mail on the internet to other domain users.

    Here I am providing you the output of "postconf -n". Please guide me
if I am doing anything wrong. Please...
