Hello Everybody,

      Here I am trying to configure my postfix mail server in following manner. 
To accomplish the same I have gone through so many online stuffs / 
documentation but still unable to configure it. So please help me to accomplish 
the same. 


I have three hosts as,

1] 192.168.1.100(mail.example.com) >> It's a virtual IP of the HA load 
balancer. 
2] 192.168.1.101(some host name)    >> Having postfix mail server installed on 
it. 
3] 192.168.1.102(some host name)    >> Having postfix mail server installed on 
it. 

      Apart from this I have hosted my own JAVA application and glassfish 
server with postfix mail server on both hosts :192.168.1.101 and 192.168.1.102. 
I have configured a virtual IP "192.168.1.100:80" on HA load balancer server to 
load balance the incoming connections to the hosted glassfish server. Whenever 
request comes from the internet on 80 port, the request will be served by one 
of the hosts 192.168.1.101 and 192.168.1.101 through load balancer. Now, from 
here the postfix mail server comes in picture. A incoming request (e.g.create 
account request) comes on 80 port and it generates a welcome mail through my 
JAVA application to send it in response to the same request. The generated 
email should be delivered to the destination through host 
192.168.1.100:25(mail.example.com) with some user authentication method.  
That's it. This is my scenario which I am trying to accomplish. So, can any one 
help me to implement it? or tell me the overall idea to accomplish the same. W!
 hat to do exactly? Is there any need to install and configure postfix mail 
server on each host?   

     Please HELP ME...!!!!
