Because, why not. **Features** - SMTP server that can accept & store valid RFC822/RFC2822 email - HTTP server/site as a client interface to the messages received **WARNING: Do not expose running server ports to open networks and do not run as `root` or an admin user! There are ZERO security features built into these servers.** Installation ------------ [](#installation) Globally: ``` $ composer global require camelot/smtp-dev-server ``` As a development dependency for your project: ``` $ composer require --dev camelot/smtp-dev-server ``` Configuration ------------- [](#configuration) Configuration is handled via environment variables. ``` SMTP_LOG_LEVEL=debug SMTP_LOG_FILE="/path/to/smtp.log" SMTP_SPOOL_DIR="/path/to/spool" HTTP_LOG_LEVEL=debug HTTP_LOG_FILE="/path/to/http.log" ``` See the `.env` file in this directory for an example if you're cloning this repository, you can create a `.env.local` file to override any of the values in the `.env` file. Use --- [](#use) Both servers have two output targets, console and PSR logger. Console output levels are managed by passing `-v`, `-vv`, or `-vvv` as options on the command line. Logger output is managed via environment variables that are used internally to configure the loggers. For example: ``` $ SMTP_LOG_LEVEL=debug vendor/bin/smtp-dev-server -vvv ``` ### Server [](#server) [![image](https://user-images.githubusercontent.com/1427081/194073098-e655ea46-bda4-4c63-8d7e-c193f4636a82.png)](https://user-images.githubusercontent.com/1427081/194073098-e655ea46-bda4-4c63-8d7e-c193f4636a82.png) To start the server, simply run: ``` $ vendor/bin/smtp-dev-server ``` This will output internal information to STDOUT.
