------------10E1748AB41B143 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit I have a LAN in the 192.168.0 range. I am trying to send mail from 192.168.0.78 (gc-infra.steenbuck.net) to 192.168.0.29 (bettchen.steenbuck.net). This leeds to 550 errors. "Host unknown (Name server: bettchen.steenbuck.net: host not found)" 192.168.0.29 is also acting as my DNS Server. Both machines have correct (or so I hope) entries in the nameserver. I can dig their names and "dig -x" their pointers. Be aware of the fact that I am not the owner of steenbuck.net and just tell my own machines that I am because I like the name. Interestingly adding "192.168.0.29 bettchen bettchen.steenbuck.net" to /etc/hosts solves my problem. I sniffed the network and gc-infra does the same in both cases. It asks DNS for the IP of bettchen and gets it. Only when bettchen is in /etc/hosts it then sends the mail otherwise not. I've googled around a bit and searched the list and found similiar problems: http://lists.freebsd.org/pipermail/freebsd-questions/2004-December/068127.html Only I do not have any kind if W2K in my LAN. And the DNS server is FreeBSD (BIND). I am lost. Has anybody an idea how I can investigate further into my problem. Thanks Hexren Attachments: maildmp_dns :ethereal compatible dump without target host (bettchen) in /etc/hosts maildmp_hosts :ethereal compatible dump with target host (bettchen) in /etc/hosts
