Trouble configuring managesive plugin for roundcube

Is there a block similar to the one above that I could add to my Roundcube config.inc.php file to enable me to use internal addresses for my imap and smtp servers?Hi yes the same ssl connection config should work in roundcube config.inc.php just use ['imap_conn_options'] and ['smtp_conn_options'] respectively. There are examples in roundcubes default.inc.php file -- Christian Kivalo
