We have been running some tests for a client and every mailing has failed the Spam Assassin filters and contains a negative score. Here is one example:
Failed some filters, with a score of -3.7.
message has a signature
HTML has a low ratio of text to image area
HTML included in message
I thought a negative spam assassin score was considered a good score and not likely spam. Even some internal tests have failed Spam Assassin. Is this a bug or is there something else I should be looking for? Thanks.
