Using authres_status v0.6.1 and roundcube 1.4.7

Could maybe be caused by a missing "minimum_stability": "dev" in your composer.json? See this repo for the requirements of the php-dkim package: https://github.com/pimlie/php-dkim

Hi; I'm getting a similar error:

Note: I added a couple of print statements to show what DIR and $autoload were returning:

                if ($uid) {
                    $rcmail = rcmail::get_instance();
                    if ($headers->others['dkim-signature'] && $rcmail->config->get('use_fallback_verifier')) {
                        if (!class_exists('Crypt_RSA')) {
                            error_log(sprintf('__DIR__=%s',__DIR__));
                            $autoload = require __DIR__ . "/../../vendor/autoload.php";
                            error_log(sprintf('autoload=%s',$autoload));
                            $autoload->loadClass('Crypt_RSA'); // Preload for use in DKIM_Verify
                        }

                        try {
                          $dkimVerify = new DKIM_Verify($rcmail->imap->get_raw_body($uid));

The require function is returning the number '1' (E_ERROR) instead of an object. Apparently __autoload has been deprecated.

At any rate, a solution is visible in the code snippet shown above: setting 'use_fallback_verifier' to false in the configuration file will skip the problem, at the expense of not cryptographically verifying dkim-signatures.

Sigh. I set 'use_fallback_verifier' to false, and the error went away, but now the message status column isn't shown in the search results.
