2009 Tax Extension, Wrong Address! Will They Accept or return?

I sent my tax extension form 4868 to the wrong address. I put going to Internal Revenue Department, Ogden UT, it should be Fresno, CA. I put the right zip, 93888-0002, but the wrong city and state! Will they return it? How do they route it, by the city and state or zip code or everything!? I don't owe anything but Ugh...2009 Tax Extension, Wrong Address! Will They Accept or return?
