Yeah, I'm fairly certain the prez doesn't answer any of his own mail. And, honestly, I don't ant him to. He's a bit busy for that.

I'm fairly certain the White House enjoys a federal dispensation from local statutes. It's probably illegal in D.C. to land a helicopter in your front yard, and have dozens of guys with high powered rifles dancing about on your rooftop, but there they are.
