Inbox policy
Each server enables its own inbox and chooses its staff role, destination channel, optional eligible-member role, and attachment count, size, and content-type policy. Closing an inbox stops new routing. These are server policy choices, not global product defaults. Discord DMs do not include a server identity. If a member is eligible for exactly one open inbox, Pup routes the message there. If more than one is available, the member must select one by starting the message with#<server id>, for example #123456789012345678 hello. Nothing is forwarded until that selection is unambiguous.
Members can send modmail stop <server id> to opt out of a server inbox, and modmail start <server id> to opt back in. A closed ticket, departed member, unavailable DM, or unavailable inbox is retained as a delivery state rather than silently opening a different conversation.
