<p>thank you again. it seems you have seen my paste of config.inc.php. I do not have a config.php:</p>
<p>my_user@some_host:/usr/local/www/roundcube/config # ls -l<br />total 67<br />-rw-r--r-- 1 root wheel 164 Jul 23 15:17 .htaccess<br />-rw-r--r-- 1 root wheel 1867 Nov 22 15:12 config.inc.php<br />-rw-r--r-- 1 root wheel 2943 Jul 23 15:17 config.inc.php.sample<br />-rw-r--r-- 1 root wheel 63790 Oct 29 20:24 defaults.inc.php<br />-rw-r--r-- 1 root wheel 2806 Jul 23 15:17 mimetypes.php<br />my_user@some_host:/usr/local/www/roundcube/config #</p>
<p><br /></p>
<p>I have tried changing tls:// to ssl:// and back again (in the line $config['managesieve_host'] = 'tls://obfuscated.domain';) but the error remains the same:</p>
