Just reading this email and also have never seen this rule before. What is the function of the soldermask alignment drc?

I can't believe I have never seen that one in there. Using "sm to sm" works for via to smd. Also a pleasant surprise, this does not give me drc's where I allow a soldermask shape to cover over pads that already have soldermasks. I'm guessing this rule will show up with occasional bogus drc's, but nowhere near as bad as if I pushed the same net button.
