Mailbox interface

Default address

A button in the mailbox interface near the current address can be pressed to set this mailbox as player's default address.
This address will then be used when mail is send to this player's name.

If the player does not currently have a default address, the button will flash, prompting a player to set it.

Sending mail

Three things are needed to start a delivery:

• Mailable item with an address tag applied to it
• Food for the pigeon (accepts any seeds)
• A pigeon

Placing mail in the sending slot and seeds in the food slot will open the front hatch of a mailbox. Nearby pigeons, that are not tired will fly to the mailbox, consume the food, pick up the mail and start the delivery process.

Front hatch will be automatically closed when either the mail or food is missing.

Receiving mail

When mail is delivered to a mailbox, it will be stored in an inbox. Mailbox can hold up to 512 item stacks of mail.

Mail can be retrieved from the inbox by clicking on it in mailbox interface:

• Click - pick up
• Shift+Click - transfer to the inventory
• Ctrl+Shift+Click - transfer all to the inventory

Hoppers will also extract mail from inbox, when placed underneath the block.

Redstone signal

Redstone comparator will output a signal strength of 15 when the inbox has any mail inside, and 0 otherwise.
