as others have pointed out, no it doesn't. the uucp server can be
configured to connect to the uucp client as well if it has a known IP
address.
you can do that, but IMO you don't want to - having the recipient poll
to pick up their mail is the right thing to do.... no need to maintain
lists of hostnames & ip addresses so that the uucp server knows where
to poll (although this could be done with a dyndns service) and no need
to waste CPU speed or bandwidth trawling the mail queue directory and
attempting to contact a host which may be down.
configured like that, the mail for a domain just gets queued in the
client's uucp spool and ignored(*) until the client site polls to pick
it up. this gets the mail out of the MTA's mail queue which would
otherwise slow down with thousands or tens of thousands of messages in
it (especially if it were a one-directory queue like sendmail's mqueue
rather than a hashed directory tree like postfix's).
(*) ignored except for a nightly cron job to bounce mail that's been in
the queue too long.
