RocksDB not working with default config for SMTP only

RocksDB not working?

2024-02-16T07:20:33.226382Z ERROR utils: Invalid configuration: Unable to find data store 'rocksdb' defined in key '[storage.data](http://storage.data/)'

The smtp-server binary does not come with RocksDB support built-in, you can recompile it with RocksDB support by modifying Cargo.toml:

store = { path = "main/crates/store", features = ["redis", "postgres", "mysql", "sqlite", "rocksdb"] }

Or you can use the mail-server binary instead.

Thanks, I added rocksdb, and it compiles alongside smtp, but I get still the same error.

If copied the config of the mail-server 1:1 and same result:

Invalid configuration: Unable to find data store 'rocksdb' defined in key 'storage.data'

If I use postgres it all works, rocksdb not.

The problem here is that you are using an invalid directory type, it has to be of type internal and then reference the RocksDb store as follows:

[directory."mydirectory"]
type = "internal"
store = "rocksdb"

[store."rocksdb"]
type = "rocksdb"
...

Okay, I use postgres now, that works, I don't know why rocksdb does not work, but for my use case it doesn't matter, what matters is Redis, and that also doesn't work:

REDIS

acl setuser stalwart on >stalwart allkeys +@all

redis.toml

[store."redis"]
type = "redis"
url = "redis://localhost"
username = "stalwart"
password = "stalwart"
timeout = "10s"
retries = 3
max-retry-wait = "1s"
min-retry-wait = "500ms"

I would also like to use rediss (TLS) but if I do that with a self signed certificate there is no configuration flag to disable SSL verification for Redis. Any ideas? It would exactly be better if you could utilize the full redis URl with username, password, DB selector, and so on, like described here: https://github.com/lettuce-io/lettuce-core/wiki/Redis-URI-and-connection-details

The Redis library that Stalwart uses is configured differently depending on whether you're using Redis or Redis cluster. I'll have this better documented, but Redis is configured entirely from the URL using the following syntax:

redis://[<username>][:<password>@]<hostname>[:port][/<db>]

And to use rediss with a self-signed certificate:

rediss://[<username>][:<password>@]<hostname>[:port][/<db>]#insecure

Edit: The Redis documentation has been updated.

Thanks, that worked like the charm. During my tests I’ve seen that many of the options available in the default configuration are not documented in the documentation. Would be nice if this would be one day on par.

Which settings have you been unable to find in the documentation?
