In answer to the question, I believe not having a control/rcpthosts
file will cause qmail to act as an open relay. Alternatively, setting
the environment variable RELAYCLIENT to an empty string for the
qmail-smtpd process will have the same effect.

Since there are valid reasons for wanting to run - and use - an open
mail relay, you don't *know* that this person doesn't want to run an
open relay. Sure, spammers will probably find - and abuse -
it. However, there are ways to deal with them, as well. Last time I
looked, ORBS was perfectly happy with you running open relays, so long
as you took one or more of those measures.
