This is called using a smart host, so you have to tell sendmail to do that.
Look for a line starting with DS, probably with a comment about smart
relay server or something like that (that's what it's called in a RedHat
sendmail.cf)

DSmailrelay.server.com

(i.e. DS<servername>)

Restart sendmail and it should work.
