what rulesets are applied to what addresses?

[Simon Kenyon]

could somebody please enlighten me as to EXACTLY which rulesets are
applied to which addresses as they pass through sendmail
(in particular the version of sendmail which calls itself 5.43)
it used to be (i think):

	envelope from:		3,1,4
	envelope to:		3,0,4
	header from:		3,1,S,4
	header to:		3,2,R,4

it appears to be different in 5.43
i need to know if sendmail puts certain addresses through the rulesets twice!

WISH: it would be nice if "envelope from:" addresses were put through a mailer
specific rule, like "header from:" addresses. that way, it would be possible
to get "from: lines" right!

who sets $g and $f?
i get lost in the code
as for the hack with UGLYUUCP...

also, what part of the result of ruleset 0 gets passed through 4?
