TLS Icon Plugin for Roundcube
=============================

[](#tls-icon-plugin-for-roundcube)

Displays a small icon after the subject line that displays the (presumed) encryption state of received mails.

- Green lock: TLS1.2 or TLS1.3 with Details
- Blue lock: Internal message from localhost
- Red lock: No encryption

Supported languages:

- English
- Hungarian
- German
- Russian
- Dutch

Configuration
-------------

[](#configuration)

Add the following lines to your `config.php`:

```
$config['tls_icon'] = [
    'header_pattern' => '(by |from \[127\.0\.0\.1\])',
    'check_pattern' => '\(using TLSv?(1\.[2-3])',
    'local_pattern' => '(mailcowdockerized-dovecot-mailcow-1|127.0.0.1)',
    'tooltip_pattern' =>  '\(using\s(.*?)\s',

];
```

and change the different patterns to match your mail server:

- `header_pattern`: Pattern to match the last hop of the mail server (e.g. `by mail.example.com`)
- `check_pattern`: Pattern to match the encryption state (e.g. `using TLSv1.2`)
- `local_pattern`: Pattern to match the local mail server (e.g. `127.0.0.1`)
- `tooltip_pattern`: Pattern to match the encryption details. Use `()` to extract details. Tooltip uses the first match (e.g. `...(TLSv?1\.[2-3])...`)

[](#credits)

Original plugin by [oszto90](https://github.com/oszto90/Roundcube_TLS_Icon_with_Hmailserver) and fork from [Takika](https://github.com/Takika/rc_tls_icon). I renamed the plugin to match the plugin naming shema and add more pattern to support more mail servers.
