poige> Yes, I saw this info here: poige> http://www.sendmail.org/m4/features.html#relay_mail_from but most poige> valuable part of my question was about the purpose or the idea behind poige> this, cause it's not too clear to me why allowing relaying for domain poige> FOO.BAR should allow relaying for SUB.FOO.BAR? 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
