I'm reading the Wiki: http://wiki.apache.org/spamassassin/WritingRules
and don't see any information on matching against envelope information... For instance, I get a lot of spam on alsa-devel@lists.sourceforge.net, and want to bias anything coming with that Envelope-Sender with a score of 4.0, since if it looks like spam on that list, it probably is... Could we add an example of using envelope info? Thanks, -Philip
