Ohh, in the case of SmartDnsHost all is *very* easy. XMail just prepare a query asking for recursion and shoot it to the SmartDnsHost. The *only* way XMail returns "recursion not available" is if the SmartDnsHost return the proper bit indicating that is not granting recursion capabilities to the host. - 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]
