README

Fork changes

In upstream, config.inc.php is ran every single time, overwriting your own config (at least with docker), so this fixes that. Also, this makes the tooltip look nicer.

Configuration for https://stalw.art:

<?php

$config['tls_icon'] = [
    'header_pattern' => 'by your.mail.server',
    'check_pattern' => 'using TLSv1\.[23]',
    'local_pattern' => '(local-hostname|127.0.0.1)',
    'tooltip_pattern' =>  '(using TLSv1.[23] [A-Z0-9-_ ]*)\)',
];

Original README

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

Add the following lines to your config.php:

$config['tls_icon'] = [
    'header_pattern' => '(by <your.mail.server>|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])...)

Original plugin by oszto90 and fork from Takika. I renamed the plugin to match the plugin naming shema and add more pattern to support more mail servers.
