Dear all,

I have 2 redhat boxes behind a gateway. I want to use unix command "mail" to
send email to my ISP email account. But it appears that I can send email
with the command "mail" in the gateway, and not the linux box behind the
gateway.

I have verified these 2 linux boxes has default gateway pointed to the
gateway:

[root@nids root]# netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0
eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0
eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.1.254 0.0.0.0 UG 0 0 0
eth0
[root@nids root]#

How can I send email from these linux boxes behind gateway?

Thanks
sam
