SendMSG – Private Messaging for Your Server

Lightweight, multilingual, and fully customizable private messaging plugin for Paper 1.21+ and 26.1+ Works on its own. No other plugin is required.

✨ Features

Optional features are OFF by default. Turn them on in config.yml. The plugin works without any of them.

🎮 How it looks in-game

When you send a message:

✉ You -> Player: Hello!

When you receive a message:

• 📺 Subtitle: ✉ You have a message
• 💬 Chat: ✉ Player writes you: Hello!
• 💬 Reply hint: → Reply with: /r (text)
• 🔊 Sound: ENTITY_EXPERIENCE_ORB_PICKUP

⚠️ All text, sounds, subtitles, and colours can be changed in the configuration files.

📋 Commands

Language codes: EN (English), UA (Ukrainian), RU (Russian)

🔐 Permissions

With LuckPerms, give these permissions to groups in LuckPerms instead of to single players.

⚙️ Configuration (config.yml)

Basics

# Plugin language: ru-RU, uk-UA, en-EN
lang: en-EN

# Delay between messages, in seconds
cooldown-seconds: 10

# Longest private message, in characters (0 = no limit)
max-message-length: 200

Features

Turn parts of the plugin on or off:

features:
  subtitle: true          # subtitle when you receive a message
  sound-receive: true     # sound when you receive a message
  sound-send: true        # sound when you send a message
  reply-hint: true        # "/r" hint below incoming messages
  clickable-reply: false  # make the hint a button (off by default)
  cooldown: true          # message cooldown
  msg-toggle: true        # /msgtoggle
  social-spy: true        # /spy
  log-to-file: true       # save all PMs to logs/private.log

Storage

storage:
  type: sqlite            # sqlite = plugins/SendMSG/sendmsg.db | yaml = ignores.yml, names.yml, offline.yml
  fallback-to-yaml: false # if SQLite cannot open, stop with an error (false) or use YAML files (true)

On the first start with sqlite, data from the YAML files is imported automatically (only if the database is empty). Changing storage.type later does not move data back. Restart the server after changing it.

Offline messages (off by default)

offline-messages:
  enabled: false          # store messages for offline players
  max-per-player: 50      # undelivered messages per player
  expire-days: 30         # delete undelivered messages after N days (0 = keep)

Link and IP filter (off by default)

filters:
  enabled: false          # turn the filter on
  links: true             # hide http(s):// and www. links and bare domains
  ip-addresses: true      # hide IPv4 addresses, with or without a port
  action: mask            # mask = replace with [hidden] | block = do not send the message

Integrations (off by default)

integrations:
  luckperms:
    enabled: false        # show the sender's LuckPerms prefix (needs LuckPerms)
  placeholderapi:
    enabled: false        # register %sendmsg_...% placeholders (needs PlaceholderAPI)

Restart the server after changing the integrations.

Discord logging (off by default)

discord-webhook:
  enabled: false
  url: ""                 # your webhook URL – keep it secret
  username: "SendMSG Spy"

Setup guide: docs/discord-webhook.md.

Sounds

sound:
  receive:
    name: ENTITY_EXPERIENCE_ORB_PICKUP
    volume: 1.0
    pitch: 1.2
  send:
    name: ENTITY_VILLAGER_WORK_CARTOGRAPHER
    volume: 1.0
    pitch: 1.0

Ignores

ignore:
  auto-expire-days: 7            # remove an ignore after N days (0 = forever)
  notify-ignored-sender: true    # tell the sender their message was blocked

Update checker

update-checker:
  enabled: true              # check Modrinth on startup for a new version
  notify-ops-on-join: true   # tell operators when they join, if an update exists

📝 Message formats

Texts are in messages/en-EN.yml, messages/uk-UA.yml, and messages/ru-RU.yml.

🚀 Installation

1. Download SendMSG.jar
2. Place it in your server's plugins/ folder
3. Restart your server
4. (Optional) Edit config.yml or messages/*.yml
5. Done! The plugin works immediately

Upgrading from 2.0.x? Your ignore lists and nicknames from ignores.yml and names.yml are imported into the new SQLite database on the first start. The original files are kept as a backup. To keep using the YAML files instead, set storage.type: yaml. Your config.yml is rebuilt from the new template on the first start: comments and layout are updated, your values are kept, and the old file is saved as config.backup-v<n>.yml. Settings that no longer exist are removed.

❓ FAQ

• How do I change the language? Use /sendmsg lang EN (English), /sendmsg lang UA (Ukrainian), or /sendmsg lang RU (Russian).

• How do I disable sounds? Set sound-receive: false and sound-send: false in config.yml.

• How do I remove the cooldown? Set cooldown-seconds: 0 in config.yml, or give players the sendmsg.bypass.cooldown permission.

• How does /ignore work? /ignore <player> adds a player to your ignore list. Use the command again to remove them. A blocked sender is told that you ignore them (unless you turn notify-ignored-sender off).

• Can ignores expire automatically? Yes. Ignores are removed after auto-expire-days.

• Can I block all private messages? Yes. Use /msgtoggle. Nobody can message you until you turn it back on.

• What is SocialSpy? Admins with sendmsg.spy can use /spy to see all private messages on the server.

• Can players message someone who is offline? Only if you turn on offline-messages.enabled. The message is shown when the player joins.

• Can I hide links and IP addresses in messages? Yes. Turn on filters.enabled. Choose mask to hide them, or block to refuse the whole message.

• Where is data stored?

  • storage.type: sqlite: ignore lists, last known nicknames, and offline messages are in plugins/SendMSG/sendmsg.db.
  • storage.type: yaml: the same data is in ignores.yml, names.yml, and offline.yml.
  • All private messages are logged in plugins/SendMSG/logs/private.log.
  • Cooldowns, /msgtoggle, SocialSpy, and last contact are kept in memory only and reset on restart.

• Does it work with EssentialsX? Yes. SendMSG handles private messages before EssentialsX, so you can use both.

• Can the console send messages? Yes. The console can use /msg <player> <message>.

• Does the plugin send data anywhere?

  • On startup, SendMSG makes one read-only request to the public Modrinth API to check for a newer version. Disable it with update-checker.enabled: false.
  • If you turn on Discord logging, every private message is sent to the Discord webhook you configure. Only turn it on if you want that.
  • Nothing else leaves your server.
