Looking at my mail streams I see evidence that spammers sometimes
add faked "SpamAssassin" headers to their messages (I assume to try
to trick recipients into thinking that the message has already been
given a clean bill-of-health).
I wrote a few test rules to look for these pre-existing "X-Spam-"
headers to test to see if it could be used as a spam detector.
However I got no hits on these rules even on hand crafted test
messages that contained such stuff.
Checking the SA source I found in PerMsgStatus.pm a line of code:
$self->{msg}->delete_header('X-Spam-.*');
that ran before any tests. So looking for SA headers inside of SA
is pointless.
So does anybody have any ideas how to test for evidence of a
prior SA pass?
