Sending External Mail

[unixgy]

Hello.

I have a Solaris 9 box I would like to send mail to external domains via mailx. I can send mail to internal local domain, but all mail directed to outside domains queue up in /var/spool/clientmqueue and do not get routed externally. We have a Microsoft Exchange mail server and I'm guessing the best way to do this is somehow run the outgoing e-mails through this Exchange server. I am also guessing this needs to be done through sendmail.cf somehow, but I have no idea how.

In summary:

mailx user@mydomain.com works fine
mailx user@yahoo.com does not work

Any help greatly apprecaited.

in sendmail.mc, "define(`SMART_HOST', `ip.of.exchange.server')"

or in sendmail.cf, "DSexchange.server.fqdn

Is sendmail running?

Thanks for the help so far, but it's still not working:

Yes, sendmail is running.

I added our exchange server (Internal FQDN) to the DS entry in sendmail.cf, stopped sendmail, re-started sendmail, and the messages are still being queued up in /var/spool/clientmqueue

Any other ideas?
