Exchange is a fine product.
I'm also wondering if it is really true that exchange 2000 or at least 2003 is an actual open relay from the start. Exchange 5.5 and lower were that way but the whole SMTP interface was changed. Anyway, the help of Exchange 2003 says: Relaying: All except the list below=20 Use this option to prevent a specific list of computers from relaying e-mail messages through the virtual server, while allowing all other computers to connect.=20 Caution If this option is selected, and anonymous access is allowed as an authentication method, any computer on the Internet that is not on the list will be able to relay e-mail messages through the virtual server. This condition is called "anonymous relay," and may result in unauthorized users relaying junk e-mail or other unwanted messages through your server. Additionally, operating an anonymous relay may be in violation of your Internet providers' terms of service.=20 This is better than a 'this is important' message. - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
