Greetings, Sendmail is bouncing mail because an MX record contains a _ in the hostname. I realize this is illegal and will notify the domain administrator. Just playing around, I noticed that I can resolve the address with host and dig, but can't ping it if I use the hostname as the argument to ping: [btt$] ping dist_internet.<rest omitted>.com ping: cannot resolve dist_internet.<rest omitted>.com: Unknown server ---- So my questions are: Is this strict enforcement of hostnames configurable? Not that I would want to leave loose enforcement on; just wondering. I noticed that linux doesn't seem to have a problem with _'s Out of curiosity, what is causing the exception? Something in libc maybe? If I turn on debug in /etc/resolv.conf, it sure looks like the lookup succeeds (all responses NOERROR), then ping just basically says forget it. ---- The system's uname: FreeBSD elvis.g-d.com 4.5-STABLE FreeBSD 4.5-STABLE #0: Sat Feb 23 12:53:56 EST 2002 root@elvis.g-d.com:/usr/obj/usr/src/sys/ELVIS i386 Thanks in advance for any insight...
