Body vs headers

[Paul Douglas Franklin of Yakima UGM]

I have noticed that spammers are putting dead giveaways into some of the 
headers which are not checked with the body rules.  Specifically, I 
received an email with a sender name that was obviously spam.  I hit 
reply so that the sender name was replicated in the body and then 
changed the to: back to myself.  When I sent it, SA flagged it as spam 
based on the presence of that sender name in the body.
I know that it treats the subject as part of the body.  Is there any way 
to have it apply all body rules to the other headers as well?
