Test your emails without ever sending them for real
A test SMTP server powered by Mailpit, installed and maintained by DINAO. Your applications send their emails to Mailpit, which captures them instead of distributing them — you inspect them in a clear web inbox, hosted in France.
What is Mailpit?
Mailpit is a test and email capture tool designed for developers. It acts as a SMTP server to which your applications send their messages: instead of distributing them for real, Mailpit intercepts and stores them, preventing any accidental sending to real recipients.
A fast, polished real-time web interface allows you to inspect each message: HTML rendering, text version, raw source, headers, attachments, and links. Mailpit includes spam checks (SpamAssassin), HTML compatibility, and link validity checks, as well as instant search.
On the integration side, Mailpit exposes a REST API and real-time WebSockets to automate your tests, offers POP3 retrieval, and a conditional SMTP relay to a real server. Lightweight and easy to deploy, it integrates naturally into development environments and CI/CD pipelines.

Technical details
You might be wondering…
What exactly is Mailpit for?
Mailpit is a test SMTP server: your applications send their emails to it instead of distributing them for real. You then inspect each message (HTML rendering, source, headers, attachments) in a clear web inbox — ideal for development and testing.
Do test emails go to real addresses?
No, that's the whole point. Mailpit captures messages instead of sending them, avoiding accidentally spamming real recipients. A conditional relay to a real server is possible as an option if you wish.
Can I integrate Mailpit into my CI/CD pipeline?
Yes. Mailpit exposes a REST API and real-time WebSockets, allowing you to automatically check email content in your automated tests and continuous integration chains.
Where are my test emails stored?
On your DINAO instance hosted in France, in an isolated container. Your test messages never leave the territory and are not transmitted to any third party.
Do I need technical skills?
Application-side configuration (pointing the SMTP to Mailpit) is simple and documented. DINAO manages the installation, security, and updates of the instance.
