I am launching Cuttlefish (https://cuttlefish.io/) SMTP process like this:
bundle exec rake cuttlefish:smtp RAILS_ENV=production
But when I try to send the test mail thru Cuttlefish's web, this process crashes with this last message:
Redis::CannotConnectError: Error connecting to Redis on 127.0.0.1:6379 (ECONNREFUSED)
What am I missing? Cuttlefish is connected to a MySQL DB, and this seems to be OK. Also, I have Postfix on the same machine, which has also been tested OK. How to make this SMTP process work?
Here is the full crash stack:
I'm listening for emails via SMTP on 0.0.0.0 port 2525
I'm in the production environment
rake aborted!
