ContactQuests

The add-on is a dedicated bridge between the Contact mail module and the FTB Quests task module. Quest items are packed into parcels and mailed to a target NPC through Mailboxes, and the mod supports custom task types built on that flow. Requirements are fulfilled only once the parcel reaches the NPC, so players must engage with the world's logistics instead of having items detected in the inventory as in standard quests.

Rewards travel the same route in reverse. Quest rewards arrive as parcels at the player's mailbox rather than appearing on click, and a Team Binding Card directs them to a team's shared mailbox when FTB Teams is in use. Custom NPC responses let a server define how an NPC replies when a player sends incorrect or extra items, including rejecting mail, confiscating items and sending easter egg replies.

ContactQuests is published for Forge and NeoForge across 3 release versions, and runs on client and server, so the server and every player need it.

Public source code and an issue tracker are available, and detailed guides are kept on the GitHub wiki.
