Because some places have only one machine (firewall) that accepts mail from the outside world for all of the hosts inside the network. For example, in my previous life as a sysadmin at WPI, only smtp.wpi.edu would accept incoming mail for all of the machines (> 3000) on campus. I'd much rather say "wpi.edu" in one place instead of listing loads of subdomains (ee.wpi.edu, me.wpi.edu, res.wpi.edu, ...). poige> I mentioned RFCs because I had a hope to find out the answer from it poige> but still haven't yet... RFC's cover protocols over the Internet, not local configuration or policy. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
