Hello!

I have this perfectly legit mail that has a +7.5 score from these three rules.

*  2.5 FRNAME_IN_MSG_XPRIO From name in message + X-Priority
*  2.5 XPRIO_SHORT_SUBJ Has X-Priority header + short subject
*  2.5 FRNAME_IN_MSG_NO_SUBJ From name in message + short or no subject

If it wasn't for the -1.9 from Bayes and -2.6 from TxRep, it would have been thrown away.

Should these XPRIO/FRNAME rules stack like this?

The e-mail in question is available here:

I checked in some changes to reduce the overlap in the FRNAME rules. The reason they are scoring that high even with overlap is those are strong spam signs in the masscheck corpus.

And: Bayes and TxRep did exactly what they are supposed to do here.

  Justice is justice, whereas "social justice" is code for one set
  of rules for the rich, another for the poor; one set for whites,
  another set for minorities; one set for straight men, another for
  women and gays. In short, it's the opposite of actual justice.
