1 year ago This is the Docker-specific location. For non-Docker installations, it is indeed /var/lib/maddy/messages.
Per https://maddy.email/docker/:
Volumes
/data - maddy state directory. Databases, queues, etc are stored here. You might want to mount a named volume there. The >main configuration file is stored here too (/data/maddy.conf).
From the actual behaviour I deduct that messages are stored under /data/messages, and this doc must be outdated?
