Hi Alexander,

Thanks for posting the link and recommeneding the correct policy.
I've changed redis.conf to use the volatile-ttl.

I am confused how the link you sent me would reduce the redis usage. It 
seems to increase it, but I admit don't know redis/rspamd well.


1. The extra redis configuration already has a dbfilename setting. Won't 
the extra file name cause problems?
# The filename where to dump the DB
dbfilename dump.rdb


2. I have now replaced my existing local.d/bayes.conf with 
ocal.d/bayes-classifier.conf. Is this correct?

OLD
# cat redis.conf
servers = "127.0.0.1";
disabled_modules = ["ratelimit","greylist"];

NEW
# cat classifier-bayes.conf
backend = "redis";
servers = "localhost";
new_schema = true;
expire = 2144448000;
lazy = true;
disabled_modules = ["ratelimit","greylist"];
