Solved Where is the mailbox?

Hello,
I recently stored a Giraffe Plush, a Red Fox Dagger, and some gold in my Bank, and then used the send mail to myself option to return these items. It says that they have been sent to my mailbox, but I am not sure where that is! My in-game stash has not received them, so I am confused where to find them. Help appreciated, and thanks!

EDIT: Haha, nevermind. It turns out the mailbox was actually in-game, on the Homeland cliffs where the shops are. I can't believe I never noticed it before, a little embarrassing! Please feel free to delete this thread.
