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?

Thank you in advance for your insight.
