We just want like ---> after the development of any server, some maximum load statistics must be made. And we want to make an analogous statistics for our case. > Actually we have made few changes in postfix source code and we are doing > performance testing on it .

Ofcourse the unmodified code is better but we modified it based on our requirements and now we are testing it too. And it is showing significant mail drops. Once we are able make the drops less we want to document the maximum load capacities of this modified server. Thatswhy we are trying to find a document which has such information so that we can do an analogous testing and documentation. Saahil > We really need guidance on this issue.
