I installed roundcube a few months ago on Hostagator shared hosting. Now I need to enable the out of office message, I see that the roundcube/plugins folders already has a folder named managesieve.
What I did this in config.inc.php
$config['plugins'] = array(
'managesieve',
);
after this I could see the "Filters" tab in Roundcube settings but when I click on it I get "unable to connect to server" message. Is there anything else that I'm missing?.
