How does this help me if:

I'm on blue.seas.upenn.edu and I want to send mail to 
myself@an.ip.address.elsewhere?

I guess I have to redo sendmail on blue?  Sorry, I don't have root on
the UPenn servers.  Yours is useful if you want to be able to send
mail to kevinfal@red without sendmail doing a DNS lookup, just
trusting /etc/hosts to know that red is red.seas.upenn.edu and the IP.
Mine is useful when you can't tweak the current machine's sendmail
config, and just want to make sure that the remote machine can accept
mail.

Also, real men edit sendmail.cf by hand ;)
