Mailboxes

Mailboxes by MrNobot
Tired of having to travel half-way across the world to give your friend(s) an item?
This plugin aims to solve this problem by adding a Mailbox System.
Including 16 different custom made Mailbox designs to match most building styles.
The plugin is completely functional in 1.20 I'm in the process of making it backwards compatible to at least 1.13 or 1.14.

How it works
Mailboxes adds a new Mailbox crafting recipe for each style of mailbox.

When a player places a Mailbox it creates a Mailbox Inventory for that player.
A player can have as many Mailboxes as they want, they all share the same storage.
Mailboxes can only be broken by the player who placed it.
Only one person can access a players Mailbox at a time to prevent the loss of items.
Right Clicking a Mailbox you own will show the Mailbox Menu, giving you the ability to open your Mailbox or open the Mailbox Selector which will allow you to open the Mailbox of another player.
Right Clicking a Mailbox you don't own will only show the Mailbox Inventory of the owner of said Mailbox.

Planned Features
More Mailbox Styles
Option to have items hand delivered by a mob
Current Limitations
Mailbox Selector will probably throw index out of bounds exception if there are more than 27 players with Mailboxes.
If a player disconnected from the server while in a Mailbox inventory it will stay locked.
Both should be fixed in next update.
paper-1.20.2-249 cause a recipe error stopped players from joining, use an earlier release like paper-1.20.2-245 until I can fix it.
