Quickstart
Install the release binary first: see Installation.
Minimal config
Create a config.toml (or a HUML config if you prefer that format):
[server]
workers = 4
pool_size = 100
max_retries = 5
[[server.listeners]]
addr = "0.0.0.0:25"
[storage]
storage_type = "fs"
base_path = "/var/lib/hedwig/mail"
Run
HEDWIG_LOG_LEVEL=info ./hedwig
Next: customize listeners, auth, DKIM, and policies in Configuration.
