Important restrictions

Inbound SMTP receiver, not an outbound email sending service or hosted mailbox. Bring your own host, domain, DNS, storage and SMTP network access; infrastructure and third-party services may cost extra. Original flashmob repository says maintenance moved to phires/go-guerrilla; review fork maintenance and secure configuration before production.
