include the time when writing the log to stderr

The daemon's configuration is by default in /etc/chasquid/, and can be
changed with the -config_dir flag.
Inside that directory, the daemon expects the following structure:
chasquid.conf
Main config file, see chasquid.conf(5).
domains/
Per-domain configuration.
domains/example.com/
Domain-specific configuration. Can be empty.
domains/example.com/users
User and password database for this domain.
domains/example.com/aliases
Aliases for the domain.
certs/
Certificates to use, one directory per pair.
certs/mx.example.com/
Certificates for this domain.
certs/mx.example.com/fullchain.pem
Certificate (full chain).
certs/mx.example.com/privkey.pem
Private key.
Note the certs/ directory layout matches the one from certbot (client for
Let's Encrypt CA), so you can just symlink certs/ to
/etc/letsencrypt/live.
Make sure the user you use to run chasquid under ("mail" in the example config) can access the certificates and private keys.
