your ip 199.144.155.166 has no reverse lookup, the one who manages the reverse dns zone (probably your provider/hoster) has to do that for you, so that 199.144.155.166 resolves to the FQDN (full qualified domain name) of your xmail machine. - 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]
