The smail.cf.sh script, which is supplied with smail-1.0, creates
a default sendmail.cf which contains the following fragment in
the "Format of Headers" section:

    HReceived: $?sfrom $s
	    $.by $j ($v/$V)
	    id $i; $b

Now, I know what the $j, $v, $V, $i, and $b variables (is that what
they're called) are, and how they are set.  Common sense tells me that
the phrase "$?sfrom $s" translates to: "If 's' is set (has value) then
type 'from the_value_of_s'".  I am assuming that $s should contain
the hostname.domain of the system I received the message from; I have
seen headers on mail sent to me which looked something like:

    Received: from bletch.UUCP by foobar.UUCP (version_junk_here)
	    id (id_junk_here@foobar.UUCP)

I find no evidence that the sendmail.cf is setting $s.  My question, then,
is where is $s supposed to be set, and how do I coerce sendmail.cf into
using it?
