Users now are are able to choose individually if they wish to receive PMs:
https://github.com/discourse/discourse/commit/22ba70fb01899ad96c933c86a7a9a651c7abd66a
Staff users are exempt from this setting, they can PM users regardless of the setting.
The setting is under “interface”:
Nice. Can admins (and/or moderators?) over-ride this feature to message users if necessary?
If I’m not mistaken, staff (admin & moderators) are allowed to send PMs to all users regardless of the user preference. @tgxworld would need to confirm.
Yes. Staffs can send PM to anyone.
I updated the OP, thanks Vinoth!
如果我的实例上找不到该选项，可能会有什么问题？我尝试了类似的词语，但我们仍然无法禁用私信 
是否可以仅从特定群组启用私信？
设置已最近更改为“允许个人消息的群组”，因此您可以为任何您喜欢的群组启用它们。
(不过，我可能把这个和你之前在聊天中问的问题弄混了 https://meta.discourse.org/chat/c/-/129/17116，这可能不是你在这里问的。:slight_smile:)
谢谢！我的错，我在查找“启用或禁用 PM”时错过了“组”的含义，就像一个机器人一样。
尝试从搜索中查找该聊天帖子但没有结果！如果需要，请删除重复项
