# Stalwart Mail Server — Local Development Configuration
#
# This is a minimal config for local dev. Production config will have:
#   - Real TLS certs (Let's Encrypt)
#   - DKIM signing with real keys
#   - SPF/DMARC enforcement
#   - Rspamd integration
#   - Hetzner Object Storage for blob storage
#
# Reference: https://stalw.art/docs
