Quick Sendmail Configuration Problem

We're looking to configure sendmail to disable the sending of mail to local recipients. Currently, our server may generate emails to, for example, personATmydomain.com. As our server is identifying itself as [login to view URL], it tries to deliver the mail locally to the user "person." As we use an external email service, we want to configure things so these email hit our MX record and get routed correctly. ## Deliverables Primary deliverable: To come up with the correct sendmail configuration such that if I run something like: mail -s "test email" < [login to view URL] it should properly be delivered to the correct mailbox (as hosted externally). Boilerplate: 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Linux (RHEL4)
