I connect my lan using 192.168.0-adresses through ppp to the net. The gateway at 192.168.0.11 calls itself arnold.neland.dk. This ip and name is naturally only known internally on my internal nameserver. When the gateway dials up, the tun0 interface gets a static ip with the name mail.neland.dk. When the sendmail on the gateway connects to hub.freebsd.org, It sends EHLO arnold.neland.dk hub.freebsd.org then replies 450 arnold.neland.dk: host not found (or something with that meaning) So I can't send mail to hub.freebsd.org. I have not met this problem before, I have sent to hub.freebsd.org before, and can still send to others. I have "fixed" this by in the outside nameserver given arnold.neland.dk the same ip as mail.neland.dk, but should this be neccesary? Should the name given in the ehlo be resolvable? I could have several mailservers behind a firewall, each presenting a different name in the EHLO-message. Surely I wouldn't have to list every one otherwise private names in the public DNS? Or should they use a "masquerade-as-in-ehlo"-option in their sendmail.cf? Leif To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
