Ok thanks turning it off works. I should edit the *.cf files or is there another way to turn it off instead of settings things up so updates kill off the setting? Anyway, I would think the rule is useful to some extent and if not, why is it included with spamassassin?
Put it in local.cf. That is where local adjustments to release rules and such should go.
Which version are you running? I had vaguely thought that this rule had been dropped a while ago for poor hitrate, but I may be confusing it with some other rules. There have been problems with both Yahoo and AOL changing their configurations enough recently to end up getting FPs on these sort of rules.
As a general thing, rules are added and scored because *at the time they are scored* they do well against spam on the test corpuses of spam. That is no guarantee that they will necessarily work for someone else with a much different mail stream, although of course we all hope that they will turn out fairly well in most cases. Also, the rules did well when they are scored. Depending on how fast things change, they may not do well at all years, months, or possibly even weeks later.
If you are not using it, you should look into turning on spamassassin updates. There are updated rule sets available for the more recent releases that will change scores and add or subtract rules to match the latest corpus characteristics.
