Kami: I've been working along similar lines but run into some difficulties. I did succeed in getting a group of managers and team leaders to suggest a list of "good words" which are often used in correspondence, and are now given negative weight. However, there is an occasional "nightmare scenario" that goes like this...
Salesperson Jones meets a potential client. Sales meeting goes well. Client seriously considering purchase of new system costing more than $10,000. Client sends email from a Yahoo account to Salesperson Jones containing text like this: "Very interested in what you described. Please call me at 10 a.m. to discuss purchase." This incoming mail doesn't contain any of our good words, and it comes from a common spam source, has other possible flaws, etc. So it gets tagged as spam and delivery is delayed. The only quick fix we've found is to assign a large negative weight to email addressed to a few in-house accounts. Of course it's not really a fix if they now get a ton of spam. I've suggested a "special word" that could be distributed to potential new clients for use in sending us email, but the idea has not caught on.
