 When Rspamd is enabled, we implicitly also start an instance of Redis in the container:
 
 - Redis is configured to persist its data via RDB snapshots to disk in the directory `/var/lib/redis` (_or the [`/var/mail-state/`][docs::dms-volumes-state] volume when present_).
-- With the volume mount, the snapshot will restore the Redis data across container restarts, and provide a way to keep backup.
+- With the volume mount, the snapshot will restore the Redis data across container updates, and provide a way to keep a backup.
+- Without a volume mount a containers internal state will persist across restarts until the container is recreated due to changes like ENV or upgrading the image for the container.
 
 Redis uses `/etc/redis/redis.conf` for configuration:
 
 - We adjust this file when enabling the internal Redis service.
 - If you have an external instance of Redis to use, the internal Redis service can be opt-out via setting the ENV [`ENABLE_RSPAMD_REDIS=0`][docs::env::enable-redis] (_link also details required changes to the DMS Rspamd config_).
 
+If you are interested in using Valkey instead of Redis, please refer to [this guidance][gh-dms::guide::valkey].

 ### Web Interface
 
 Rspamd provides a [web interface][rspamd-docs::web-ui], which contains statistics and data Rspamd collects. The interface is enabled by default and reachable on port 11334.

 ### DNS
 
 DMS does not supply custom values for DNS servers (to Rspamd). If you need to use custom DNS servers, which could be required when using [DNS-based deny/allowlists](#rbls-real-time-blacklists-dnsbls-dns-based-blacklists), you need to adjust [`options.inc`][rspamd-docs::config::global] yourself. Make sure to also read our [FAQ page on DNS servers][docs::faq::dns-servers].
