authres_status plugin for roundcube
This plugin checks the Authentication-Results headers that were added by your MTA and displays an icon to show the verification status. Parsing of the Authentication-Results headers is more or less done according to RFC5451 which supports DKIM, DomainKeys, SPF, Sender-ID, iprev and SMTP AUTH result values.
This plugin is partially based on dkimstatus by jvehent, which was based on a plugin by Vladimir Mach.

Install
If not using composer, copy all files to your plugins/ folder and add 'authres_status' to your $config['plugins'] array in config/main.inc.php or config/config.inc.php.
Configuration
If you want to enable the results column in your message list, enable this in your settings. You can also choose which statuses you would like to see/ignore.
As of version 0.2 you can also enable an internal DKIM verifier (php-dkim by angrychimp) if your MTA did not add a Authentication-Results header. You could experience some slow down because we need to retrieve the whole message body of each message for which we run the verifier.
Tested
Tested on Roundcube 1.0.0, let me know if it works on previous version as well
