Right, if "UUCP hosts" means "all hosts listed in the UUCP maps", not just "all hosts that communicate via UUCP". There are machines that don't talk UUCP that are listed in the maps, so a smart mailer can still route mail through them without the sender being aware of it. > On the other hand, it is good advice for internet hosts that are *not* > also UUCP hosts, since they would not normally be expected to use ! as > a routing operator. You mean, some machine might have "!" as a character in user names? I assume nobody is actually doing this, in which case it doesn't really matter. --- Tom Fitzgerald Wang Labs fitz@wang.com 1-508-967-5278 Lowell MA, USA ...!uunet!wang!fitz
