If that behavior is meant on one server, it would be enough to deny relaying. However, Courier sets RELAYCLIENT by default upon login and it doesn't seem that the value of that variable can be set in advance to something special in order to limit an authenticated user. Thus, I'd say you need a global filter. That is fully generic, since you may code a definition of what local addresses are allowed. When the filter detects a forbidden destination, it can reject the message after the DATA, which will result in an error in the user's SMTP client. Obviously, you need a firewall that prevents local users from reaching the destination host on the internet directly. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
