Modmail for Discord

A bot for Discord that allows users to DM the bot to contact the server's entire mod team. These DMs get relayed to a modmail server where each user gets their own channel, or "thread". Moderators and admins can then reply to these threads, and these responses are relayed back to the original user as a DM.

Inspired by Reddit's modmail system.

Commands

Anywhere on the modmail inbox server

!logs <user> Lists previous modmail logs with the specified user
!block <user> Blocks the specified user from using modmail
!unblock <user> Unblocks the specified user from using modmail

!anonreply <text> Sends an anonymous reply to the user in the format "Role: text" (alias !ar)
!close <time> Closes the modmail thread. If a time is specified, the thread is scheduled to be closed later. Scheduled closing is cancelled if a message is sent to or received from the user.
!logs Lists previous modmail logs with this user
!block Blocks the user from using modmail
!unblock Unblocks the user from using modmail
!!shortcut Reply with a snippet. Replace shortcut with the snippet's actual shortcut.
!!!shortcut Reply with a snippet anonymously. Replace shortcut with the snippet's actual shortcut.
!move <category> If allowMove is enabled, moves the thread channel to the specified category
!loglink Shows the link to the current thread's log
!suspend Suspend a thread. The thread will act as closed and not receive any messages until unsuspended.

To automatically reply without using !reply or !r, enable alwaysReply in the config. alwaysReplyAnon sets whether to reply anonymously. If you do not wish to reply, it will ignore any message starting in the prefix (which defaults to !), such as !note
