__ marks rules that are partial rules.  Therefore, you are taking it out of context by running it in a standalone capacity.

I'm aware that it marks any email that has digits in the body.  My plan is to change it to {3,6} because my theory is that the number emails all have numbers greater than 3.  If you or others have input on this fact, I'd like it to hear it.  However, I have received very few of these emails though I have definitely tracked their passing on numerous servers.  

Rules are a gradual process for me.  I build rules, refine, test and then move then eventually if I feel it has mass-desire, I move it into the SA rulesrc sandbox for further testing and promotion on the SA Nightly Mass Checks.  But, taking a partial rule and claiming it has False Positives and using it against me is bad evidence.  If you can point out a false positive/negative caused by the rule as a whole, I'm open to suggestions and comments, but I really feel quite attacked over what was trying to be a helpful.

In the meantime, I'll submit the rule to the SA sandbox for masschecks on it earlier than I would have with 1,6 and we'll see what the SA corpus response is like for FPs.  The committed revision was 412731.
