I have a fresh install of Ispconfig 3.1 and I keep getting: No E-Mail - Server found! I have a roundcube login but I can't login.
When I click the mail icon on the control panel. I changed the link to roundcube and still got the same message.
Check the roundcube configuration file in /etc/roundcube/ and ensure that the settings for the smtp and imap server are correct in that file.
I did these tutorials now I have a white screen when I sign in: https://www.howtoforge.com/tutorial...l-pureftpd-bind-postfix-doveot-and-ispconfig/ https://www.howtoforge.com/tutorial/roundcube-installation-on-debian-8-jessie/
check your webserver error log. If you have reinstalled using the same server name maybe your browser has bad data cached too, try clearing your browser cache and cookies and restarting it if the error log doesn't find anything.
