Forgot to say that the box is Red Hat 9!
Did you want to send a mail to that address to begin with?
In any case, the problem seems to be that you don't have a valid hostname configured, and thus the recieving host doesn't want to accept the mail (since it can't verify that the sending address is valid).
Can you help me with this valid hostname then please :)
Well, it depends very much upon your network design and a lot of other things...
How is this computer connected to the internet, and how does your network look, etc.? Do you have a registered domain name that you want to use or anything?
Yes, I have a no-ip address I wish to use, this PC is connected to the net, and on the lan it is the only linux box on there, at ip 192.168.0.10
In that case, if the system is going to act as a server for that no-ip domain name, you should set the hostname to that no-ip name. Enter it into the /etc/sysconfig/network file (like "HOSTNAME=domain.no-ip.org").
Thanks a lot Dolda2000 :)
