 Starting from rspamd 1.0, we propose to use `sqlite3` as backed and `osb` as tokenizer. That also enables additional features, such as tokens normalization and

 Rspamd allows to learn and to check multiple classifiers for a single messages. This might be useful, for example, if you have common and per user statistics. It is even possible to use the same statfiles for these purposes. Classifiers **might** have the same symbols (thought it is not recommended) and they should have a **unique** `name` attribute that is used for learning. Here is an example of such a configuration:

 From version 1.1, it is also possible to specify redis as a backend for statistics and cache of learned messages. Redis is recommended for clustered configurations as it allows simultaneous learn and checks and, besides, is very fast. To setup redis, you could use `redis` backend for a classifier (cache is set to the same servers accordingly).
