I want to load balance outbound emails between 3 post-fix gateways for sending mails only reason is to use multiple different source IPs to increase throughput & inbox delivery. Each gateway should receive an approximately equal amount of outbound messages.

How is it possible please suggest.

                    +----------> smtp A ---------> Internet
                    |                                  
clients --------> smtp lb -----> smtp B ---------> Internet
                    |                                  
                    +----------> smtp C ---------> Internet
