Would it be possible to provide an address that receipts could be forwarded to? Similar to how Tripit works where you forward travel plans to [e-mail] and they are connected to your account based on the sender address. Reciepts could still be sent automatically by creating an auto forward rule.

Most people use Gmail, which doesn't have auto-forward capabilities. (intentionally, I think)

You can auto-forward if you can confirm ownership (or at least control, by clicking a link) of the address.

False. Forwarding is an action you can set on any filter.
