No. The real action 3 is "if a smart host is defined give the mail to
them. If not, bounce it." Aggressive rerouting is a seperate option
and, if defined, is performed before your (1).

In smail 3.0 (which has no aggressive routing!) the order is:

	(1) If you're BSD, check if the destination is an Internet
	    address like [10.1.7.9].
	(2) If you're BSD, check the nameservers or host table for
	    the destination machine.
	(3) Check for a route in the paths file.
	(4) See if destination machine is listed by "uuname"
	(5) If a smart host is defined, give it to them. If not,
	    bounce it.

And before anyone asks, smail 3.0 is still alpha testing (it's at
Smail3.1.7.2 right now).
