I have installed ISPConfig 18.104.22.168 based on instructions here for Ubuntu version 12.04. Evertything was working fine until I did an upgrade. Now I am trying to get the email portion working. When I try to login into squirrelmail I get this "Error connecting to IMAP server: localhost. 101 : Network is unreachable". When I check the Status of Service in ISPConfig I get all services OFFLINE. Just to be clear I had email and working server prior to upgrade and my fiddling trying to get it to work again. Thanks!
