The question I have is how do you know after the fact, which db host the command actually executed against? Is there a way to retrieve the machine name from the load balanced set of machines?

  I have a mailing list application that sends emails through several dedicated SMTP servers (running Linux Debian 5 and Postfix) in the same network of a hosting company. However, the application is using the servers' external IP addresses in order to connect to them over SMTP, and I was wondering what kind of improvement would be obtained if the application used the internal IP addresses of the servers instead?
