Mail Server expert to fix emailing over back connect proxy to balance server load

Mail Server expert to fix emailing over back connect proxy to balance server load
Check and fix problem of sending mails from my dedicated server by implementing backconnect proxy with subnets. In other words, SERVER LOAD BALANCING.
Requirements for BACKCONNECT PROXY - in other words, SERVER LOAD BALANCING
I need a Back Connect Proxy for SERVER LOAD BALANCING and also redirect traffic via the proxy.
I will then access this proxy thru SEND command, where the first 3 numbers of the ip is static but 4th is dynamic (123.123.123.*) but using varied port numbers say from 1000 to 250000.
When I want to use the proxy I will have to connect from the end-user insterface via SEND command to proxy which will redirect the traffic via the proxy. (Back connect)
- Proxies can only be accessed by my server only (COMMANDSERVER), i.e. 123.123.123.*:1000 thru 250000, each port represents a different proxy IP and Port
Example, lets say I send email message from my server, when you check email sources, you should be able to see the proxy ips:port from which messages were sent and NOT MY SERVER IP.
Received: from [[login to view URL]] (port=1279
Received: from [[login to view URL]] (port=44961
Received: from [[login to view URL]] (port=50033
Received: from [[login to view URL]] (port=22813
Lets say back connect server has ip: [login to view URL], when I will connect to a proxy I will use [login to view URL]
Back connect server will have ports from 1000 to 250000 opened. Also an option to allow connection based on IP or domain name.
If someone tries to connect to the Back connect server and he is not in the allowed ips he cannot connect.
For those who understand what Back connect means I wont have to explain this more.
