Two comments:  The "-d21.12" on the command line is just a nicety which
provides you with more specific output; the sendmail -bt is the important
part.

Secondly, calling rulesets after S0 from sendmail -bt won't do quite what
you want it to do.  The problem is that S0 resolves to something like

$# tcp $@ host $: user < @ host >

And if you pass that into S4, it won't necessarily behave right.  You have
to explicitly pass only the $: portion.  So the sequence for To: (Envelope)
is more like this.  (Note that this takes advantage of the IDA feature
that -bt does not automatically call S3 first.  It's more challenging
without this.

	% /usr/lib/sendmail -bt
	> 3,0 user@host
	rewrite: ruleset  3   input: "user" "@" "host"
	rewrite: ruleset  3 returns: "user" "<" "@" "host" ">"
	rewrite: ruleset  0   input: "user" "<" "@" "host" ">"
	rewrite: ruleset  0 returns: $# "tcp" $@ "host" $: "user" "<" "@" "host" ">"
	> 2,n,4 user<@host>
	...

You get the idea.
