No problem.  Use Smail 2.5 and Deliver 2.0.  (You all KNEW this was
coming.)  Configure Smail to use Deliver for both local mail and UUCP.
Install a paths database on machine2 that only says:

	.uucp		machine3!%s
	machine1	machine1!%s
	machine2	%s

And install a complementary file on machine1.  Then write a post-user
delivery file for Deliver that translates "machine[12]!user" into the
appropriate network incantation -- something like this:

	for u
	do
	    case "$u" in
	    machine[12]!*)
		m=`echo "$u" | sed -e 's/!.*$//'`		# Machine
		x=`echo "$u" | sed -e 's/^[^!]*!//'`		# User
		echo "|/usr/lib/sendmail -oem -oi '$x@$m'"	# use SMTP
		;;
	    *)
		echo "$u"
		;;
	    esac
	done

Tadaa!  Instant mixing of network and UUCP transports.  Smail knows
who talks to who, but it doesn't have to know the transport method for
each connection -- that's handled by Deliver.
