Redis is used as a key-value store for rspamd's and (some of) mailcow's settings and data. If you are unfamiliar with redis please read the introduction to redis and maybe visit this wonderful guide on how to use it.

Client

To connect to the redis cli execute: === "docker compose (Plugin)"

``` bash
docker compose exec redis-mailcow redis-cli
```

=== "docker-compose (Standalone)"

``` bash
docker-compose exec redis-mailcow redis-cli
```

Debugging

Here are some useful commands for the redis-cli for debugging:

MONITOR

Listens for all requests received by the server in real time: === "docker compose (Plugin)"

``` bash
#docker compose exec redis-mailcow redis-cli
127.0.0.1:6379> monitor
OK
1494077286.401963 [0 172.22.1.253:41228] "SMEMBERS" "BAYES_SPAM_keys"
1494077288.292970 [0 172.22.1.253:41229] "SMEMBERS" "BAYES_SPAM_keys"
[...]
```

=== "docker-compose (Standalone)"

``` bash
#docker-compose exec redis-mailcow redis-cli
127.0.0.1:6379> monitor
OK
1494077286.401963 [0 172.22.1.253:41228] "SMEMBERS" "BAYES_SPAM_keys"
1494077288.292970 [0 172.22.1.253:41229] "SMEMBERS" "BAYES_SPAM_keys"
