You can get this same effect without caring about the port number. Just require SMTP-AUTH for relaying. This is easily achieved, you just remove any hosts you don't directly control from your relay domain(s). That means your clients (no matter which port they're using) will have to use SMTP-AUTH to relay out to the outside world. Hosts that don't use SMTP-AUTH (no matter which port they connect to, and without regard to whether they're a client or a remote relay) will have to be sending to your local recipients.
You are correct, technically. However, I believe part of the justification for port 587 was to ensure that the customer was able connect, regardless of incoming mail traffic. It's supposed to be a separate process that outside mail servers don't use. -- Jason 'XenoPhage' Frisvold [EMAIL PROTECTED] http://blog.godshell.com
