A player to player mail system for Bukkit Minecraft servers

by defxor

Allows creation of text note items and sending of letters to players no matter if they're online or offline. The letters are delivered by postmen at intervals specified in the config file, and letters can be stored and handled as any other item for later reading. We wanted something that not only allowed us to pass notes to each other, but also felt like it was part of the regular Minecraft environment.

We believe we succeeded.

Courier in-game screenshot Framed Letter


/letter [text]
Creates a Courier Letter with the supplied text. Hold the Letter in your hands and write /letter [text] again to add more text to the Letter. Use &nl or \n to insert newlines. Multiple page Letters are supported, use right-click and left-click to turn the page.
/post [playername]
Sends the Letter held in your hands to another player, name verified to be a player on the server. Depending on the config, the received Letter will be privacy-locked to that player (can be unlocked by simply adding text to it with /letter).
/courier fees
Lists the fees, if any, that apply for sending mail or creating letters
/courier unread
Requests re-delivery of all unread mail, even if they have been delivered to you before. Courier knows the difference between a mail having been delivered and actually read, and this is meant to be used in the cases where you've managed to misplace the Letter without having read it first.
Intended for OPs only, if postman delivery happens seldom and you want to force one to appear. NOT NEEDED in actual gameplay.

To receive messages, simply poke the friendly postman when he appears or right-click him to receive the message directly into your hands or inventory.

The strings "%loc" and "%pos" will be replaced with the current X,Y,Z position in any Letters written, if surrounded by spaces.

In addition to the above all user visible strings can be edited. Some translated configs are available in the translations folder as well in the plugin data folder. Move and rename them to 'config.yml' to use.


As you've understood (and seen if you've looked at the in-game images) I use Maps to render Courier Letters. If you're a plugin developer and your plugin handles maps and you either want to make sure your map system isn't screwed up by Courier Letters, or maybe if you want to handle Courier Letters in a special way, you can easily identify them:

The actual Maps used by Courier to render Letters ALWAYS have their X coordinate set to 2147087904 (or INT_MAX - 395743, if you want).

The ItemStacks(Material.MAP) that point to those Maps are Enchanted with DURABILITY and the enchantment level is used as a database key to find the matching text.

Release history

(see the Changelog for detailed information)

Known issues

  • Moving Letters between slots in creative mode (/gamemode 1) causes them to become empty later (eg. after logout/login)
    • This seems to be a Bukkit issue, please do not handle Courier Letters in creative mode until this is better understood.
  • Courier does not support extended character sets, it will skip such input when writing Letters.
    • This is due to Bukkit Maps only supporting the 'old' standard Minecraft Font. If support is extended in Bukkit I will implement it into Courier as well.
  • ... and all open tickets and issues, of course.

Future development

This plugin is looking for a new maintainer. The original author does not play Minecraft any longer. The update to Minecraft v1.8 could only be made thanks to a pull request having been made at Github. Do not expect any future development until a new maintainer can be found.


I made this plugin for our own use at a private server. If you like it, and feel you want to show appreciation other than just posting a message, you can throw some bitcoins at this address: 1GA8XDDwxeSvHAbuySY9TnnBXNMqriEYcP

    We had the same problem, our letters didnt show anything. The problem was, that we tried to save the maps in our mainworld like before the update to 1.8.8.. During 1.7.9., our mainworld=spawnworld. But with 1.8.8, we created a new spawn world. We needed to transfer the maps to the Spawnworld data and then it worked. Maybe this helps you, too. :)

    Thank you we love this plugin on our server!

    I cam seeking some help. The link to the resource list is not working and I was wondering if any in the community knew the tag needed to use black ink as resource needed for letters.

    Thank you in advanced.

    C.o.p Staff.

    Many thanks for that info - as you indicate there I see no immediate ways to work around that issue.

    With 1.8 Mojang made the minecraft client cache the canvas of a particular map (based on map id) on world change, causing it to cease updating thereafter until relogging. This affects vanilla minecraft as well. I've made a more detailed ticket here:

    @TanderMME: Go

    Last time I checked there was no support for non-Latin characters in Minecraft/Bukkit for rendering to Maps and Courier can only use what's available. If anyone else wants to check whether that has changed during the last few years I would absolutely merge a pull request :)

    (It's MinecraftFont.Font that's used)

    @thequestingbeast: Go

    If you look inside your plugins/Courier folder, in the file messages.yml, is the actual letter content there?

    The only way I can help if it is is to send you a version with debug printouts available to see what Courier does under the hood.

    I went from 1.1.9 to 1.2.1 and all the letters now show the preview in your inventory and look enchanted, but holding them has nothing to be seen.

    hi, I'm from Russia, I would like the support of the Russian language, just if you write in the letter text in Russian, there's just nothing is displayed.

    It should not happen. From which version are you upgrading and how do you do the upgrade? Nothing has changed in how Courier reads its database in the v1.8 upgrade versions.

  • Avatar of thequestingbeast thequestingbeast Jun 06, 2015 at 16:44 UTC - 0 likes

    When I update to the 1.8 versions old letters can no longer be read. Is this something I am doing or can it be avoided?
