I saw a question regarding this, and there are 4 links to apple's TechInfo pages on the subject at:

However, I do have a question: Isn't there a way to disable SMTP relaying without having to specify every single IP address / host that can send to your users? I cannot see it being too feasible for someone to have to call you to add their email host to your sendmail configuration each time someone wants to send you an email.
