Depending on their connection type, specify an IP range under the relay tab of your Virtual SMTP Server(s).

The issue is that if I allow relaying all remote users are able to send and receive email. However if I have it this way I am susceptible to spammers. (already happened once, never again) When I stop it from allowing relaying no remote users are able to send email. Instead they receive an NDR saying that relaying is not allowed. I am using exchange 2000 with the latest service pack and Outlook Express for the clients. I suspect that I need to alter the way I have it setup. Is there a step by step guide to seting up Exchange for pop3/smtp clients? Regards...
