 ## Users cache
 
-MongooseIM used to feature a cache to check whether a user exists, that was unavoidably enabled, and had no eviction policy, that is, the cache could continue growing forever. Now, MIM features a module called [`mod_cache_users`](../modules/mod_cache_users) that implements a configurable cache policy, that can be enabled, disabled, and parametrised, per `host_type`. This might not be enabled by default in your configuration, so we recommend you verify your configuration and enable it if needed.
