Selective spam filtering?

In V4, it will be something like

Spam Checks = /usr/local/MailScanner/etc/rules/spam.checks.rules

then in that file
To:     account1 at domain.com     yes
To:     account2 at domain.com     yes
To:     account3 at domain.com     yes
To:     *@domain.com            no

Then it will do spam scanning for account1,2,3 and not for any of the other
accounts at domain.com.

For those of you that are wondering, this is the form of the generalised
ruleset configuration system in V4, with which you can pull all sorts of
useful tricks (yes, you can even make that outgoing mail directory
(/var/spool/mqueue) dependent on the addressing of the message, so you can
send incoming mail into 1 queue while sending outbound mail into another
queue if you want to). There are a few other rule types other than the 2
above, leaving you the ability to test on just about anything to do with
where the mail came from or where it is going.

I haven't yet managed to come up with the reason *why* you might want to do
some of the more obscure configurations that are possible, but I'm working
on it :-)
