I think that sendmail is set with relaying  denied to all except localhost by default. If you are trying to send from a machine on your lan, try adding the machines details to /etc/mail/access.

The default access file should look something like this:

localhost.localdomain           RELAY
localhost                               RELAY
127.0.0.1                             RELAY

Which allows sending mail only from those addresses.

You will need to add something like this for each of the machines that you want to send mail from:

192.168.1.137	RELAY

Hope this helps.
