I don't see how SpamAssassin's header lines would make a difference.
The header lines are appended to every message that is checked by
SpamAssassin whether it is flagged as spam or not.  If your ISP/mail
sever uses SpamAssassin, then all of your email messages will have a
SpamAssassin header in them.  This information is clearly not useful for
our purposes of spam classification.  What is interesting is the
probability of the "{SPAM?}" (without quotes) string that SpamAssassin
sometimes adds to messages that it classifies as spam.  I think we
should get rid of all those headers and maybe have an optional parameter
allowing us to get rid of the "{SPAM?}" string in the subject line so
they do not interfere with bogofilter's detection.
