I'm having trouble telling my server to relay all the outbound email to my SBC YAHOO SMTP server.

As instructed by http://www.tnpi.biz/internet/mail/toaster/faq/messsage-routi ng.shtml

But that doesnt show me how to input my username and password. Help will be greatly appreciated. Also, I read from elsewhere that in order to relay with auth, we have to patch qmail with that function.
