Fix email issues on CWP Control Panel

I have moved hosting from GoDaddy to Linux CWP for my existing domain. The website transfer is successful, however i am having issues with the emails. I have added same email address (as in the previous host), but I am getting an IMAP error upon trying to sign in. Even when I am logged into CWP, and attempt to autologin via Roundcube, I am getting an error 'Connection to storage server failed'. I need someone who can provide a prompt solution for this and help fix this email issue.
