Hi all, I did a brand new fresh install of a Perfect Server Ubuntu 16.04 LAMP (Without ISPconfig) and also added a virtual users and domains setup using MariaDB, Postfix and Courier, following the guides in the howto section. When I try to login with webGUI Roundcube, the status indicator just keeps going but it does not make it into the inbox, It just stays on the roundcube login screen When I try with thunderbird on my laptop, the cert acceptance window continually popups up endlessly but it doesn't login into the inbox. Any help would be greatly appreciated. Regards
