# Tiny MailCatcher
Tiny MailCatcher is a _tiny_ (<6 MB) drop-in [MailCatcher](https://mailcatcher.me/) replacement
optimized for size and speed. It's meant to be run in a resource constrained environment, such
as a CI system, or as part of an automated test suite.
Some features that the original MailCatcher has were omitted: Tiny MailCatcher does not have
an HTML + JavaScript UI and it does not publish a WebSocket endpoint at /messages (yet).
If you need either of these features I strongly recommend installing the original MailCatcher.
When Tiny MailCatcher is running any emails sent to port 1025 (configurable) can be accessed
and analysed via a REST API. This is useful in a test suite when asserting that certain emails
are or are not sent.
## Documentation
The documentation at [https://mailcatcher.me/](https://mailcatcher.me/) also applies to Tiny
MailCatcher.
In short:
1. Tiny MailCatcher has an SMTP server which runs on port 1025 by default (configurable)
2. There is a REST API that runs on port 1080 (configurable).
- `GET/DELETE http://localhost:1080/messages` retrieves/deletes all messages
- `GET http://localhost:1080/messages/:id` retrieve a single message in JSON format
- `GET http://localhost:1080/messages/:id.source` retrieve the message source
- `GET http://localhost:1080/messages/:id.html` retrieve the HTML version of this message
- `GET http://localhost:1080/messages/:id.eml` retrieve the EML version of this message
- `GET http://localhost:1080/messages/:id.plain` retrieve the text/plain version of this message
- `DELETE http://localhost:1080/messages/:id` delete a message
- `GET http://localhost:1080/messages/:id/parts/:cid` retrieve attachments by content ID
