Go-Guerrilla is a lightweight SMTP server daemon written in Go, designed for receiving large volumes of email quickly and efficiently. It can be used as a standalone daemon or embedded as a package, with a modular processor backend for custom mail handling.

Use cases

• run a lightweight smtp server to receive email
• accept inbound mail without full mta sending features
• build a disposable email service like guerrillamail
• store incoming email in mysql or redis
• chain custom processors to validate recipients and save mail
• receive large volumes of email on a multi-core server

When to choose

• you only need to receive email, not send it
• you want a memory-safe, high-performance smtp daemon in go
• you need a modular, extensible mail processing pipeline
• you want config hot-reloading and multiple smtp servers sharing one backend

When to avoid

• you need a full mta with sending and relaying capabilities
• you want a turnkey mail server with imap/pop3 and webmail
• you need actively maintained software with guaranteed upstream support
