Using SCO 3.2 5.0.6 with sendmail configured. I have ISP DNS servers defined in the resolv.conf file. I also have an MS EXCHANGE server setup on the network. If I issue the following command:

echo "hello" |mail username@mycompany.com

The user specified receives e-mail through the MS Exchange server. If I issue the following command:

echo "hello" |mail somebody@yahoo.com

The user specified does not recieve the mail, and a message is returned stating that yahoo.com is an unknown host. I can ping yahoo.com by name.

What am I missing?
Thanks in advance.
