You have to increase "max_mail_processes" as this code emits the error
message:

        if (mail_process_count == set->max_mail_processes) {
                i_error("Maximum number of mail processes exceeded");
                return MASTER_LOGIN_STATUS_INTERNAL_ERROR;
        }

[...]
> max_mail_processes: 1024
[...]

But the question is: how much user are accessing your server
simultaneously? Is it really more than 1024 or is mail_process_count wrong?
Your overpowered server is surely able to handle more than 1024 connections.
