Interpostal Mod by Multicoder

This mod is a very primitive mail system for servers.
You have stamps which you use with a command to set the recipient,
And you have the mailbox in which to both send and receive items to other players.

There is no fancy GUI for the mailbox, just simply hold what you want to send and right click the box, You can right click while sneaking to retrieve the item in case you put the wrong thing in there.

Before placing your mailbox, please use /post mailbox * (where * is what you want the mailbox to be called), The mailbox's name will change to the name and will be green to show you it is ready to be placed.

You no longer need to use the coordinates of the mailbox to send post to other players. You now only need the name of the mailbox instead.

Next is the stamp. As long as you know where it is going use /post stamp * (where * is the name of the receiving mailbox) while holding the stamp in your main hand, once done the stamp's name should turn green.

Finally right click your mailbox with the stamp to send it to the other mailbox, you will get a very simple message saying "sending item" and if the recipient is online they will get the message "You Have Mail From {user}" with your name replacing the {user}

The crafting recipes are extremely simple on purpose. For the mailbox, put logs around the 3*3 grid like you are making a chest and place one ender pearl in the middle. This will give you A mail box.

for the stamps, put paper around the 3*3 again like making a chest and place a stick in the middle. This will give you 16 stamps.

And that is it. No really it's that easy.
