           Summary: Re-order header stripping so that rules can look at
                    headers before stripping
           Product: Spamassassin
           Version: SVN Trunk (Latest Devel Version)
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: spamassassin

Currently it is my understanding that SA will strip what it believes to be 
previous SA headers from a message before rule processing.

Situation: There is a current spam form going around that includes very 
specific bogus SA headers.  These headers claim the message as not spam.  While 
this claim has no effect on SA itself, it has been shown to confuse other 
transport and filtering programs that interact with SA, which was probably the 
spammer's intent.

The proposal is that the SA rules should be able to see these possibly bogus 
headers before they are stripped.  The particular headers involved here are 
sufficiently unique that quite reliable rules could be written to give the 
message an extra 5 points or so due to the presence of one of these headers.  
This would largely if not completely defeat the spammer's original intent.

However, currently rules to catch this are not possible, because the data is 
gone before the rules run.
