[comp.mail.uucp] How does "routing" responsibility work?

pst@comdesign.uucp (Paul Traina) (07/21/88)

I may be wrong about this,  but I was under the impression that any
gateway into a domain is responsible for being able to connect to (or at
least route to) any other host in that domain.

How does one take (the simplest example) mail from:
	foo.la.ca.us to bar.la.ca.us

Assuming foo does not know about bar?  Do we then pass the mail back
up to the "ca" router and it finds & computes a new path to bar?

To believe that what is true for you in your private heart is true for all
