UltiMail - In-Game Mail System

UltiMail is the mail system module for the UltiTools ecosystem, providing a full-featured player-to-player mail system for Minecraft servers.

The current module version is 2.0.0, requiring UltiTools-API 6.3.0 or later. Upgrade the framework first, place UltiMail-2.0.0.jar in plugins/UltiTools/plugins/ and restart fully; /ul reload does not load a new JAR.

Feature Overview

UltiMail provides a complete in-game mail system for your server. Players can send text messages to both online and offline players, and attach items from their inventory as mail attachments. When a recipient logs in, they receive a clickable notification about unread mail that opens the inbox directly. Mail content and attachments can be browsed and claimed through a paginated GUI. Administrators have the ability to broadcast mail with attachments to all players at once. The module also includes a player recall system that sends in-game mail to all registered players, and can optionally send real emails via SMTP to bring back players who have been away.

Installation

Method 1: Install via UPM (Recommended)

/upm install ultimail

Method 2: Manual Installation

1. Make sure UltiTools-API 6.3.0 or higher is installed on your server
2. Download UltiMail-2.0.0.jar
3. Place the JAR file in the plugins/UltiTools/plugins/ directory
4. Restart the server

Quick Start

After installation, players can start using the mail system immediately via commands. Here is a typical workflow:

Send a mail to Steve:

/sendmail Steve Hello

The system will prompt you to enter the mail body content. Once you finish typing, the mail is sent automatically. Type cancel at any time to abort.

Send a mail with an item attachment:

Hold the item you want to send in your main hand, then type:

/sendmail Steve HereIsASword attach

The system will take the item from your main hand and include it as an attachment. Administrators see a multi-item selection GUI instead of taking from the main hand.

View your inbox:

/mail inbox

This displays a text list of all your mail, showing read/unread status and attachment indicators.

Browse inbox via GUI:

/mail read

This opens a paginated GUI. Unread mail appears as a "Writable Book" icon, read mail as a "Book" icon. Click any mail to read it and claim attachments.

Usage Tutorials

Scenario 1: Sending a Letter to a Friend

You want to tell your friend Alex about a mining trip tomorrow:

1. Type /sendmail Alex MiningTomorrow
2. The system prompts: Please enter mail content (type 'cancel' to cancel):
3. Type: Let's meet at the usual spot at 3 PM tomorrow. Bring your diamond pickaxe!
4. The mail is sent automatically and you see a confirmation message

Even if Alex is offline, they will receive a notification when they next log in.

Scenario 2: Sending an Item to a Friend

You want to give a diamond sword to Alex:

1. Hold the diamond sword in your main hand
2. Type /sendmail Alex ASwordForYou attach
3. The system takes the sword from your hand and prompts you for the mail body
4. Type something like Use this sword to slay the dragon!
5. The mail along with the item is sent successfully

When Alex receives the mail, they can use /mail claim 1 (assuming it is mail number 1) to receive the sword in their inventory.

Scenario 3: Admin Broadcasting a Maintenance Notice

As an admin, you want to notify everyone about tomorrow's maintenance:

/mail sendall ServerMaintenanceTonightAt2AM

If you also want to include compensation items for everyone, use:

/mail sendall MaintenanceCompensation items

A 45-slot selector opens, accepting at most min(max-items, 45) stacks (default 27). Shift-click or drag into the attachment area, then confirm to broadcast.

Scenario 4: Managing Mail via GUI

1. /mail read opens the inbox GUI
2. Unread mail shows as a "Writable Book" icon, read mail shows as a "Book" icon
3. Click a mail entry: it is automatically marked as read; if it has attachments and you have inventory space, items are claimed automatically
4. Use the pagination buttons at the bottom to browse pages, and the close button to exit
5. /mail sentgui opens the sentbox GUI to check the status of mail you have sent

Scenario 5: Recalling Inactive Players

Your server just had a major update and you want to bring back old players:

/recall Server1.21MajorUpdate

The system automatically sends in-game mail to all registered players. If you have enabled SMTP email in the configuration, real emails will also be sent to players who have an email address on file.

FAQ

Q: What if the plugin doesn't work after installation?

A: Check the following:

• Confirm UltiTools-API version is 6.3.0 or higher
• Confirm the JAR file is in plugins/UltiTools/plugins/ (not the root plugins/ directory)
• Check the server log for a UltiMail has been enabled! message
• If installed via /upm install, a server restart is required for it to take effect

Q: Config changes not taking effect?

A: After modifying plugins/UltiTools/pluginConfig/UltiMail/config/mail.yml, use /ul reload to reload the configuration. No server restart is needed. An out-of-range number refuses module loading at startup. During /ul reload, the entire change to this configuration file is refused and the old running values are kept, including other settings in the same file. The file is not automatically rewritten. Correct the invalid value, then reload again. A new JAR still requires a restart.

Q: How to set up permissions?

A: UltiMail uses the standard Bukkit permission system. You can assign permissions with any permission plugin (such as LuckPerms). For example:

• Allow all players to use mail: ultimail.use and ultimail.send (grant explicitly to players)
• Prevent a player from sending mail: revoke the ultimail.send permission
• Allow admins to broadcast mail: grant ultimail.admin.sendall

Q: Can regular players attach multiple items?

A: No. Regular players using the attach parameter can only attach the item in their main hand. The system automatically takes it from their hand. Admins with the ultimail.admin.multiattach permission get a multi-item selection GUI that accepts the smaller of max-items and 45 stacks (default 27).

Q: What happens if I delete mail with unclaimed attachments?

A: It won't happen. If a mail has unclaimed item attachments, the delete operation is blocked and the system tells you to claim attachments first. Batch delete operations (/mail delall and /mail delread) automatically skip mail with unclaimed attachments.

Q: What if my inventory is full when claiming attachments?

A: The system checks for sufficient inventory space before claiming. If there isn't enough room, it tells you how many empty slots are needed and does not drop any items.

Q: Does the recall feature require UltiLogin?

A: No. The recall feature will try to get the registered player list from UltiLogin first (if installed), but even without UltiLogin, it falls back to mail records and the server's offline player data. Real email sending does require players to have bound their email in UltiLogin.

Q: Does SMTP email sending require additional setup?

A: Recall uses the server's existing JavaMail (javax.mail) environment and the email settings in config/mail.yml. A missing library is reported as a real-email failure in the console; in-game mail is unaffected. This upgrade does not require changing the JAR, switching provider or rotating SMTP credentials.

Upgrade, Language and Attachments

This page describes UltiMail 2.0.0. mail-expire-days never took effect: this module has no mail expiry and keeps mail until a player deletes it. messages.new-mail and messages.mail-sent were never read either. Existing files are not stripped of those keys; startup and every module reload warn, and you may delete the unused keys.

The join notice and sent confirmation come from notify_new_mail (keep {0}) and mail_sent_success (keep {RECEIVER}) in lang/<language>.yml in the same module folder. To customize, copy the official file to lang/en-myserver.yml, edit the copy and set language: en-myserver in the UltiTools main configuration. Edits in official files are restored at start or module reload, with the edited file kept as .bak. Do not paste the old {COUNT} or {PLAYER} placeholders across.

The six text settings for messages.mail-received, recall titles/content and server name follow language at startup and /ul reload while they remain built-in text; operator-edited values stay. Change at least one character to keep a built-in text without having it follow language. Edit them in config/mail.yml; editing an extracted language file does not replace these configuration values. Framework-written comments also follow language, while custom comments stay.

The selector has 45 attachment slots, but its limit is the smaller of max-items and 45 (default 27). Shift-click from your inventory and dragging into the attachment area are supported. An over-limit move is refused and the item stays in your inventory; the bottom button row accepts no items. Closing without confirming, cancelling, unloading, or ending the content prompt without sending (any case of cancel, the 120-second timeout, quitting and similar endings) returns attachments; overflow drops at your feet. A refused send and excess items at confirmation are returned the same way. Before mail creation these items exist only in memory, not as a promise of crash recovery.

Attachment claims and attached commands record their state first. A failed claim record gives nothing; a failed command record runs nothing and asks you to read again. On a GUI click the attachment is claimed first and the commands run next tick, in written order. Failed or unknown commands are logged, do not stop later commands and are not individually retried. A mail left unfinished by an older version may run its commands once more on its next read. Direct /mail read <number> timing is unchanged. Failed deletion reports that it was not saved; batch deletion continues and reports successful and unsaved counts separately. This is not an exactly-once guarantee across servers or crashes.

Known Limitations and Reload

The final subject word attach and final broadcast-content word items are attachment switches. Reword text that needs to end with that word. A switch without content sends nothing and shows help. Explicitly writing messages as {}, ~ or null keeps that empty value and uses default text; non-Chinese servers may also log two extra save warnings without overwriting values. To allow default child keys, leave nothing after the colon in messages: or write mail-received explicitly.

Run /ul reload UltiMail (or global /ul reload) to re-read configuration and language for subsequent mail. Unusable values warn; conditional-component toggles need a restart when the framework reports drift, since reload does not create or remove components. New JARs always need a restart. Recall continues using your existing mail environment; this upgrade introduces no SMTP rotation or new provider prerequisite. Do not edit plugin.yml inside the module JAR to configure email.

Changelog

v2.0.0

Changed

• This version requires UltiTools 6.3.0 or later and raises api-version in plugin.yml from 620 (the released 1.1.0 declaration) to 630. Upgrade UltiTools before replacing the module JAR; older frameworks refuse this module at load with a warning that the UltiTools version is outdated, naming UltiMail. This module uses DataOperator.updateCounted, which frameworks 6.2.1 to 6.2.5 do not provide (UltiKits/UltiMail#7, UltiKits/UltiTools-Reborn#544).

• plugin.yml now declares identify-string: ultimail, the key of this module's entry in the UltiCloud catalogue. The framework's update check and /upm update skip a module that does not declare it, so this module now takes part in both: a later published version carrying the same key is reported at startup and can be installed with /upm update (UltiKits/UltiTools-Reborn#474).

• Message and title settings in config/mail.yml — the new-mail notice (messages.mail-received), the server name recall mails carry (recall.server-name), and the recall mail and email texts (recall.subject, recall.content, email.recall-subject, email.recall-content) — are written in the server's language when the module starts, and the file is what the module shows (for example recall.subject: '[{SERVER}] Come back to us' and recall.server-name: Minecraft Server under language: en); previously they were fixed Chinese text, so language: en had no effect on the new-mail notice or on recall mails. A setting that is still built-in text — in any language, or a default an earlier version shipped — follows language: it is rewritten when the module starts or after /ul reload. A setting you edited is kept, so a recall.server-name you set to your server's name stays as it is. To keep a built-in text but stop it following language, change at least one character (UltiKits/UltiMail#22). The text written is this module's built-in text: edit these settings in config/mail.yml; an edit of the extracted language file does not change them (earlier versions never read them from the language file either). The new-mail notice names the sender {SENDER}, as before.

Fixed

• A mail change whose stored row has been removed in the meantime is now reported as not saved, on every storage type. If an administrator deleted a mail from storage, or another server on a shared database did, while a player had the mailbox open, clicking that mail still marked the claim as saved and handed over the attachment (and ran its attached commands) from a mail that no longer existed. Now the claim is refused with Your claim could not be recorded, so nothing was given. Please try again., the attached commands do not run, and the failure is logged; marking a mail read and deleting a mail log it the same way. Before, only the JSON storage reported a missing row, with an error (UltiKits/UltiMail#44).

• A mail's attached commands now run on the server tick after you click the mail in the mailbox (/mail read) instead of inside the click. The framework now runs a command at the moment it is dispatched, so an attached command that opens or closes a GUI (/kits, another module's menu, /mail sentgui) would otherwise have run inside the click event, which Paper does not allow, and could fail or leave the mailbox in a broken state. The mail is still recorded as run before anything runs, a command that fails is still logged and does not stop the ones after it, and the commands still run in their written order and only once. The attachment claim in the same click now happens first, so an attached command that gives items can no longer take the inventory slots the claim needs. /mail read <number> typed as a command is unchanged (UltiKits/UltiMail#43).

• config/mail.yml now writes its comments in the server's language. Twenty comments (every setting in the file) used to be Chinese-only, so a fresh install under language: en got a file with Chinese comments. Each is now a language-file key that the framework resolves in the server's language every time it writes the file, with an English and a Chinese entry in lang/en.yml and lang/zh.yml. On an existing server the comments the framework wrote on these twenty settings, the Chinese ones earlier versions wrote included, switch to the server's language at the next start, and after you change language and run a bare /ul reload; values are untouched, and a comment you wrote yourself is kept as you wrote it (UltiKits/UltiTools-Reborn#611) (UltiKits/UltiMail#42).

• The attachment selector (/sendmail <player> <subject> attach for a sender with ultimail.admin.multiattach) now takes items by shift-click from your own inventory, into the first free attachment slot, and by dragging into the attachment area; before, both were refused and only a plain click placed an item. When the page already holds as many attachments as it accepts (max-items, at most 45), a shift-click or drag that would add one is refused with Too many attachments! Maximum <n> items and the stack stays in your inventory; for /sendmail … attach that limit is now max-items (default 27), the same limit the send is checked against, where the window used to allow 45. A drag into the bottom button row is still refused (UltiKits/UltiMail#32). This check replaces a shift-click guard that could never fire (UltiKits/UltiMail#26).

• /mail delete, /mail delall and /mail delread no longer stop part-way when the storage cannot record a deletion. /mail delete answers The mail could not be deleted because the storage did not record it. Please try again.; delall and delread carry on with the other mails, report how many they deleted, and add <n> mail(s) could not be deleted because the storage did not record it; they are still in your inbox. Please try again. Before, a database error escaped the command after some mails were already deleted and the player saw only a generic error (UltiKits/UltiMail#38).

• A value inserted into a console line or a recall mail is shown exactly as written: every placeholder of the line is filled in one pass. Before, a value containing a later placeholder was rewritten — a server installed under a directory whose name contains {KEY} or {REASON} got a removed-key warning naming a path that does not exist, a failed recall email whose error text contained {EMAIL} named the wrong address, and a recall.server-name containing {SENDER} or {PLAYER} had it replaced in recall mails and emails (UltiKits/UltiMail#37).

• A mail's attachment and its attached commands are now recorded as claimed before they are handed over, and a claim that cannot be recorded is refused instead of being repeatable. When the storage cannot record the claim, /mail claim and the mailbox window answer Your claim could not be recorded, so nothing was given. Please try again. and give nothing; when it cannot record that the attached commands ran, none of them runs and the reader is told to read the mail again. An attached command that fails, or that the server reports as not run (an unknown command), is logged with the mail and the command, is not run again, and no longer stops the commands after it. /mail claim on an attachment that cannot be read now answers This mail has no attachments! instead of reporting 0 items claimed, and a storage error while marking a mail read is logged instead of aborting the read. A mail whose attached commands an earlier version left unfinished (a command that failed part-way, or a failed record) runs them once more when it is next read, then never again. For plugins that call MailService, claimItems keeps its signature and returns no items for a refused claim; the new claimAttachment also tells a refused claim apart from one with nothing to claim (UltiKits/UltiMail#31).

• /mail help now lists /mail sentgui, and each help line shows its command once, as does the attach line of /sendmail help. Those lines used to print the command twice, because the language file's help text already starts with it (UltiKits/UltiMail#21).

• language: en now applies to the unread-mail notice another module can send through UltiMail's mail service, which was fixed Chinese text (UltiKits/UltiMail#21), and to everything /recall prints — the permission refusal, the progress and summary lines and its help — and to the recall mail and email text (UltiKits/UltiMail#22). The three commands' descriptions (shown by /help) follow language too.

• The join notification now shows the real unread count, one pair of brackets around [Click to view], and colour where it used to show & codes: it read &e[Mail] &fYou have &a{0} &funread mail(s)! [&e[Click to view]]. Clicking it still opens the inbox (UltiKits/UltiMail#24).

• The enable line on the console now follows language (it looked up a Chinese sentence that no language file carried), and under language: zh the join notification's hover text comes from the Chinese language file (UltiKits/UltiMail#28). language: zh also applies to the console lines that were fixed English text: a failed mail read, claim, command run, update or item conversion, a failed recall email, the missing-UltiLogin line of /recall, a selector that cannot be closed when the module unloads (now logged through the module's own logger), and the warning about a key this version no longer reads. Their English wording is unchanged, except that the warning for a leftover messages.new-mail no longer says the notification leaves the count out.

• Reloading this module (/ul reload UltiMail, or /ul reload for every module) now re-reads config/mail.yml and refreshes the language files, so an edited value such as max-subject-length applies to the next mail without a restart. Previously this module's reload method replaced the framework's and only logged a line, so neither step ran. UltiTools 6.3.0 also reports @ConditionalOnConfig drift and logs its own per-module reload line at this point (UltiKits/UltiMail#20).

• Unloading this module (/upm uninstall UltiMail) now runs the framework's command unregistration and then its listener unregistration, so the module's commands are really removed and its listeners stop firing. Its unload hook returns items from open attachment selectors before the listeners are removed. Previously this module's unload method replaced the framework's and only logged a line, so after /upm uninstall UltiMail both its commands and its listeners stayed active until the server restarted (UltiKits/UltiMail#20).

• An item placed in the attachment selector is now given back when that GUI is closed without clicking Confirm — the selector reached by /sendmail <player> <subject> attach for a sender holding ultimail.admin.multiattach, and by /mail sendall <content> items. Previously the item was destroyed: the module recognised the closing page by the inventory's holder, which the GUI library always leaves empty, so the code that gives items back could never run. The items come back exactly once, and any stack the sender's inventory no longer has room for is dropped at their feet instead of vanishing (UltiKits/UltiMail#27).

• The three other points where a mail attachment is handed back now also drop what no longer fits at the sender's feet instead of destroying it: the items above max-items when Confirm is clicked, a content prompt that ends without sending, and a send the server refuses (for example an unknown receiver). Each of these previously discarded whatever the sender's inventory could not hold (UltiKits/UltiMail#27).

• Unloading this module (/upm uninstall UltiMail) now hands back every item still sitting in an open attachment selector, and closes that selector, before the module stops listening. Previously those items were destroyed: the code that gives them back runs from an inventory-close event, and unloading the module unregisters its listeners, so no close event could reach it. An item placed in that GUI exists only in memory until the mail is created, which is why there was nothing to recover afterwards (UltiKits/UltiMail#27).

• An attachment waiting at the content prompt is now given back whenever that prompt ends without the mail being sent, however it ends: typing cancel in any capitalisation, the prompt's 120-second timeout, the sender leaving the server, or another plugin ending the prompt. Previously only the exact lower-case word cancel gave it back. Typing Cancel or CANCEL ended the prompt by a different route, printed nothing at all, and destroyed the attachment — so a sender who held one copper ingot, ran /sendmail <player> <subject> attach and then typed Cancel was left with no ingot, nothing on the ground and no mail. The sender is now also told their send was cancelled on every one of those routes, instead of only some of them (UltiKits/UltiMail#27).

Removed

• 27 language-file entries that no code displayed, from lang/en.yml and lang/zh.yml: the gui_* page and button words (the pages use UltiTools' own), the delete_confirm_* lines (there is no delete confirmation page), the send_* lines that other entries replaced (input_content_prompt, mail_sent_success, error_no_item_in_hand), attachment_gui_title, lore_subject, lore_items_count, error_no_permission, sendall_no_permission (a permission refusal comes from UltiTools' own message), arg_number, arg_content and notify_mail_received (the new-mail notice is messages.mail-received in config/mail.yml, whose built-in text is mail_received); and notify_hover_hint from lang/en.yml, whose text the join notification now reads from notify_hover_text.

• The module's own console lines on unload and on reload (Chinese sentences meaning "UltiMail disabled!" and "UltiMail configuration reloaded!", printed in Chinese under either language setting), and the never-consulted mail_disabled and mail_reloaded language keys that described them. UltiTools 6.3.0 logs one reload line per module (Module 'UltiMail' reloaded.) (UltiKits/UltiMail#20).

• The mail-expire-days setting in config/mail.yml (default 30). It never took effect in any version: nothing read it, this module has no mail expiry of any kind, and a mail was always kept until a player deleted it, whatever the value. Mail behaviour is unchanged. Removing the setting is not a rejection of mail expiry: a real implementation, which among other things has to decide what happens to a mail whose attachment was never claimed, is tracked as a feature request in UltiKits/UltiMail#34. A server upgraded from an earlier version keeps the key in its mail.yml, because the framework never deletes a key from an operator's file; while it is there, the module logs one warning at startup and on every reload of this module (/ul reload or /ul reload UltiMail), naming the file and the key, and the key can simply be deleted (UltiKits/UltiMail#23).

• The messages.new-mail and messages.mail-sent settings in config/mail.yml. Neither ever took effect: nothing read them, so editing them never changed what a player saw. The unread-mail notification on join and the confirmation a sender gets after sending already take their text from this module's language file, entries notify_new_mail and mail_sent_success in lang/<language>.yml beside the config folder, so they follow the server's language setting. To customise them, copy the official language file to one whose name starts with its language code and a hyphen (for example lang/en-myserver.yml), edit the entries there and set language: en-myserver in plugins/UltiTools/config.yml; an edit made in the official file itself is restored at the next start or module reload, the edited file kept as .bak (UltiKits/UltiTools-Reborn#616). Their placeholders differ from the removed keys': notify_new_mail carries {0} where the old key used {COUNT}, and mail_sent_success takes the receiver's name as {RECEIVER} (not {PLAYER}); text pasted across with the old placeholder is refused by the framework, which then uses the bundled text. The join notification now fills {0} with the unread count (UltiKits/UltiMail#24). Removing these unused settings does not change what players see. messages.mail-received, the setting for the message an online receiver gets when a mail arrives, is read and stays. A server upgraded from an earlier version keeps both removed keys in its mail.yml; while either is there, the module logs one warning for it at startup and on every reload of this module, naming the file, the key and the language entry that now holds the text, and the key can simply be deleted (UltiKits/UltiMail#23).
