I have the same question because I am at Rosewood Firehouse. I move a mailbox to the location the notice stated the package arrive but it is not by the mailbox i placed.

Has anyone tested, going into admin mode, and COPYING the mailbox and taking it back to an area that doesnt have one..... to see if the code just "sends to closest mailbox"? I would but I am dealing with a few issues right now.

Same question

would like to know also before i get this mod

Alright, so I can answer this now. If you do not have a mailbox address or location for your building, on the "View your cart screen" when you go to finalize your purchase, the top section has address to deliver to. You can click on a push pin up there and it will give you a square that you must walk out and select to be your deliver point......this needs to be a blank square, and when you do that even though you are outside now, it will pop back up to the "View your cart screen" and you can check the payment type and click order now. The products will be delivered to that square until you restart the server again. On server restart you will have to re-pair the square with the ordering PC.
