# prevent_credential_leaks

This plugin prevents an authenticated user (via SMTP AUTH) from sending
their username and password out in a message (e.g. like replying to a
phish).

If their username and password are detected inside the message body, then
the message is rejected with the message:

```
Credential leak detected: never give out your username/password to anyone!
```

Note that if the username is qualified e.g. user@domain.com - then the
plugin will search for both `user` and `user@domain.com` for maximum
effectiveness.

## Configuration

No configuration is required. Simply add the plugin to your `config/plugins`
file. It should be added before any other plugins that run on hook_data_post
for maximum efficiency.
