I don’t think you have any legal responsibility to actually deliver it to her. If she wants it so badly, she should have to come get it herself once you have gotten it out of your mailbox. So, I’d simply tell her, “once I get to my mailbox, I’ll give you a call and you can come get it”. I wouldn’t worry about making a special trip for her convenience though. This is all my opinion though, you might want to check with someone else about the actual legal end of things.
