My theory is that the mailbox from the short is actually another portal. The other dimension chose to make it look like a mailbox is because they worship mail! The mailman from the first episode is a guide for people from his dimension. The scout lady looking for the mailman, she is a "scout". She wants to communicate with her dimension. The mailman can guide her to the mailbox where she can send a message to one of their prophets, who answers questions that are sent through a mailbox shaped portal.
