Well, you MUST (RFC2505, 2.1) prevent unauthorized use of your mail server as a mail relay. So if your question is "since my local users don't have to authenticate themselves against my mail server, is there a rule that says I can't offer unauthenticated SMTP service to roaming users", I guess the answer is "yes, there IS actually a rule forbidding that." Cheers, D
Derek, there is a subtle difference between the words you SHOULD and you MUST. The RFC you quoted is a "Best Current Practices" document. You know, like "The Surgeon General had determined that [insert your favorite vice here] is bad for your health". i.e, he can't order you MUST stop smoking, maybe you SHOULD consider it because yadayada. Now let's go back to 1997 and see how this baby was born. In Sep 1997, on this very list, Paul Vixie was known to have laid the seed: `Could somebody who hasn't been burned to a crisp by IETF politics please write a "Mail Relay Requirements" RFC that we can brandish at these vendors? (Dave Crocker seems like a logical choice for this given his past credits.)' Full text of the message at http://www.dotcomeon.com/relay_default.html
