Could you clarify what you mean by this? I get tables and the general architecture just fine, but I don't understand what you mean by an owner-alias. I'm assuming a trivial lookup of key=myl...@example.com, with 300,000 "values", presumably all external email addresses. Or perhaps I'm misinterpreting this, given that you're referring to local recipients. I'm not sure why re-evaluating the alias would cause multiple delivery (that's what the other recipients won't appreciate, right?)
