Actually, ALL of cts.com is gateway'd through 'crash' on UUCP. The MX record points to trout.nosc.mil (an Internet host that forwards mail to 'crash'). >Obviously, psuvm.psu.edu does have an MX record... Not so obvious. psuvm.psu.edu is directly connected to the Internet (has an 'A' record) - psuvm.psu.edu A = 128.118.56.2, 128.118.84.2, 128.118.85.2, 128.118.101.2 It's also PSUVM on BITNET - which means it's its own gateway :-) Don't ask me why it needs FOUR IP numbers -- I only know what the nameserver tells me. /s Murph [Internet] or ...{psuvax1 or mcvax}!uconnvm.bitnet!sewall [UUCP] + Standard disclaimer applies ("The opinions expressed are my own" etc.)
