I believe AOL add the same header as spamassassin, which they use when other 
AOL users receive said email to put in spam folder unless the correspondent 
is known to recipient.

Blocking email that claimed to be spam based on these headers turned out to 
have a very high false positive rate.

I tweaked the header_check as others have described, but eventually abandoned 
fiddling with headers and just ignores the whole X-Spam-Flag as I'm not using 
spam assassin.
