You can't route based on the sender, you can only route for destination ( smtpfwd.tab ). And it's domain based, not user based. You cannot run two instances of XMail on the same machine also. You have to setup another XMail machine and you have to tell those users to use such machine as SMTP server. You'll configure this machine by only having custom domains ( the ones that you handle ) that "smtprelay" to you main ( POP3 ) machine. At this point you can setup source routing on your firewall. - Davide - 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]
