mod_muc_rtbl: also filter messages This was a bit tricky because we don't want to run the JIDs through SHA256 on each message. Took a while to come up with this simple plan of just caching the SHA256 of the JIDs on the occupants. This will leave some dirt in the occupants after unloading the module, but that should be ok; once they cycle the room, the hashes will be gone. This is direly needed, otherwise, there is a tight race between the moderation activities and the actors joining the room.

summary: Limit rate of outgoing unsolicited messages
---

Introduction
============

This module limits the rate of outgoing unsolicited messages from local
clients. Optionally, unsolicited messages coming in from remote servers
may be limited per s2s conneciton. A message counts as "unsolicited" if
the receiving user hasn't added the sending user to their roster.

The module depends on [mod\_track\_muc\_joins] in order to allow sent
messages to joined MUC rooms.

Configuration
=============

To set a limit on messages from local sessions:

``` {.lua}
unsolicited_messages_per_minute = 10
```

To enable limits on unsolicited messages from s2s connections:

``` {.lua}
unsolicited_s2s_messages_per_minute = 100
```
