The Honey Danber version of uuxqt puts the sending host name in the UU_MACHINE environment variable. This value has been authenticated by UUCP and so if unforgeable (assuming that Honey Danber is configured correctly). The BSD4.3 version of UUCP probably has something similar. If it doesn't, maybe it should be added. -- Matt Costello <matt.costello@SanDiego.NCR.COM> {sdcsvax,cbatt,dcdwest,nosc.ARPA,ihnp4}!ncr-sd!matt
