Stan is referring to smail version 1.0, which did not know about headers.
The current version of smail, 2.3, will add the necessary headers if they
aren't already there.  In fact, 2.3 is so much improved over 1.0 that
System V machines no longer have any reason to bring up sendmail just for
the sake of domains - smail by itself handles headers, forwarding, and
mailing lists just like sendmail.  Since it also allows default routing
to a smarter host, smail 2.3 is especially well suited to a PC class machine
(running UNIX, Xenix, etc.  If you want MS DOS, get UULINK.)

Smail 2.3 will be posted to mod.sources Real Soon Now.
