That condition is not likely to occur, but it would be great if
spammers "abused" it :-). The X-Spam-Flag will only exist in messages
that SA thinks are spam. If a spammer sticks it in, then they are
finally being nice and advertising that the message is spam.

Right. At one point it had that condition, but I removed it when I
was testing some SA rules (and wanted my locally generated mail to be
scanned). No doubt I've just confused you, but see below for a
historical explanation.

If you don't want these messages to be checked use this condition :
condition = "${if and { {!def:h_X-Spam-Flag:} {!eq {$received_protocol}{spam-scanned}} {!eq {$received_protocol}{local}} } {1}{0}}"

If you want these messages to get checked, then use exim4 and move the
spamcheck router to the top of the list. You might be able to get
exim3 to do this too, but it isn't quite as simple an orthogonal.
It's neat to see how when you share something it can come back even
better. Those comments and some of the specific config options were
part of what I came up with and published at
http://dman.ddts.net/~dman/config_docs/. Nigel then improved it and
sent it back to the list. The docs have just been updated. (in case
you're wondering how I can talk about the history of the comments in
Nigel's config :-)).
