When I send it to an external email address, such as yahoo, the message delivered successfully. Of course, I'm doing the configuration behind a firewall. I'm using a relay too, and I did declare the relay host in 'SMART_HOST' in the sendmail.mc file and have also recompiled it to produce the sendmail.cf. I also restarted the sendmail service.

Is ana.boeing.com your machine, the relay, or the target MX receiver? Whatever
it is, it thinks it should be able to deliver mail to boeing.com locally, but
doesn't have a mary.y.wang user or alias.
