For the record, after 25 years, Wildcat! SMTP (or did Wildcat! UUCP) have

What problem does it solve?
One problem in definitely solved was detecting mail loop as soon as it's
practically possible, without having to wait until a message ping-ponged a
bunch of times between servers. You still need to count Received: headers,
but most mail loops get broken right away.
Beyond that, it offered mail handling software a means to avoid the need for
explicit configuration of their mailbox address. They'll just pick it up
from the Delivered-To: header, and run with it. This is much easier than
picking apart the bits of the topmost Received: header, looking for the
"for", and hoping to find one.
