I could add another point between BAYES_999 and BAYES_99 scores but that seems reactionary. Is there a better way? Should I thrown in another point for certain keywords in marketing emails like these?
For this specific message I might be inclined to add a rule to check for a URL in the subject and add a point for that. I can't think of very many legit mails I've ever received with a URL in the subject. A point or two for that should be safe enough if it isn't spam, but could trip it over the edge if it is.
header URI_IN_SUBJECT Subject =~ /\b[-\w\._]+\@(?:[-\w_]\.)+(?:com|org|biz|cloud)\b/
score URI_IN_SUBJECT 1.5 describe URI_IN_SUBJECT A URI in the subject of the message Something like that, maybe. Loren
