Yeah, you're correct in that assumption.

I've only really ever heard of the box outside of someone's home being called a postbox or mailbox. Despite the fact that both terms also refer to the box at the post office where you can put outgoing mail, there's just no separate word for them. And I've only ever heard of the slot on the house door where the mail is placed being called a mail slot.

Letterbox is a completely new term to me in this context... and I still am not quite sure what it would mean, if not a mailbox. Haha.
