Physical mail doesn't have a history, so why should "housemail"? It expires after k days, you need to forward it to a personal address if you want to save it. "Housemail" doesn't need to receive arbitrary information, only information that can't be shifted to personal email because there is no registration step. So e.g. things that aren't opt-in, and things where you are legally expected to check what you receive. So, traffic tickets, backup communication from utilities (e.g. water is getting turned off), etc. I think constraining it to only the necessary use cases makes it a lot simpler than what you are imagining.
