mod_isolate_host: handle server-generated stanzas The hook for setting the no_host_isolation is only called for c2s sessions. This does not work for stanzas generated by the server, such as PEP notifications or presence probe answers. To handle that, we do per-stanza checks for the case that the origin is local.

# mod_muc_batched_probe

This module allows you to probe the presences of multiple MUC occupants or members.

XEP-0045 makes provision for MUC presence probes, which allows an entity to
probe for the presence information of a MUC occupant (or offline member).

See here: https://xmpp.org/extensions/xep-0045.html#bizrules-presence

This module creates the possibility to probe with a single IQ stanza the
presence information of multiple JIDs, instead of having to send out a presence
probe stanza per JID.

The IQ stanza needs to look as follows:

```
   <iq from="hag66@shakespeare.lit/pda"
      id="zb8q41f4"
      to="chat.shakespeare.lit"
      type="get">

      <query xmlns="http://jabber.org/protocol/muc#user">
         <item jid="hecate@shakespeare.lit"/>
         <item jid="crone1@shakespeare.lit"/>
         <item jid="wiccarocks@shakespeare.lit"/>
         <item jid="hag66@shakespeare.lit"/>
      </query>
   </iq>
```



## Configuration

Under your MUC component, add `muc_batched_probe` to `modules_enabled`

```
   Component "conference.example.org" "muc"
      modules_enabled = {
               "muc_batched_probe";
      }
```
