Overview
Mailpit is an email and SMTP testing server that intercepts outbound mail from your applications so nothing reaches real recipients. It presents every captured message in a fast web interface with HTML, text and raw views, attachments, headers and spam checks. Teams use it to inspect and debug transactional email during development and staging.
Why the cloudimg image
The cloudimg image runs Mailpit under systemd behind nginx with WebSocket support for the live message list, hardened and ready within minutes of launch. A unique UI password is generated on first boot as a bcrypt htpasswd credential and stored in a root only file, and captured mail is kept in SQLite on a dedicated resizable disk. Backed by 24/7 cloudimg support.
Common uses
- Email debugging
- Staging mail capture
- Transactional email QA
