【问题描述】：
我正在运行具有以下 mod_muc 配置的 ejabberd（18.3.0 版）服务器：
mod_muc:
host: "conference.@HOST@"
...
default_room_options:
allow_subscription: true
persistent: true
mam: true
我正在尝试从各种客户端访问此服务器上的 muc 房间（带有 xmppframework 的 ios，带有 node-xmpp-client 的 js - 手动制作 xmpp 命令）。客户端能够接收消息 - 仅当我在连接后发送 presence 消息时。
但是，如果不发送存在，我不会在客户端收到任何消息（即使订阅 成功）。我的理解是接收消息不需要 presence 消息（对于 mucsub）。
非常感谢任何帮助！
回应巴德洛普回复的更多细节
我将客户端/服务器上的 xml 消息与您发布的消息进行了比较。继续您使用的 user1/user2 示例，我看到 user2 的订阅成功：
<iq xmlns="jabber:client"
lang="en"
to="rk3@localhost/abcd"
from="tr21@conference.localhost"
type="result" id="D7550060-E2AE-4369-878C-261A02BA48A2">
<subscribe xmlns="urn:xmpp:mucsub:0" nick="rk3n">
<event node="urn:xmpp:mucsub:nodes:messages"/>
<event node="urn:xmpp:mucsub:nodes:presence"/>
</subscribe>
</iq>
另外，来自 user2 的 muc 服务查询结果如下：
<iq xmlns="jabber:client"
lang="en"
to="rk3@localhost/abcd"
from="conference.localhost" type="result" id="B28A237A-5D54-4AE2-821A-195272B05A88">
<subscriptions xmlns="urn:xmpp:mucsub:0">
<subscription jid="tr21@conference.localhost"/>
</subscriptions>
</iq>
但是，当我从 user1 发送群聊消息时：
<message
from="rk1@localhost" to="tr21@conference.localhost"
type="groupchat">
<body> hi there777hi there778</body>
</message>
User2 仍然没有收到上述消息。
我在 ejabberd 服务器上打开了日志级别 5，可以看到服务器正在尝试将上述消息发送给 User2 (rk3)。但是，我在服务器上看到的这条消息的最后一条日志如下（我没有看到这条消息的任何“Send XML on stream”日志）。

我可能遗漏了一些非常基本的东西（w.r.t user / nick / muc room 等），但不知道是什么。
您能否告诉我您在服务器上创建 user1/user2、注册他们的昵称等的步骤（使用 ejabberdctl）？
