Hi Amit,
At first glance your memory usage seems OK. You have approx 6GB of ram as
cached.
Is your new server set to sync time with an ntp server? Dovecot is very
sensitive to drift in clocks.

Good suggestion, Bharath. That didn't occur to me off hand.
That's a honker of a host, Amit. Care to share numbers? Like number of users,
emails.

Are you able to connect to IMAP from localhost? Or using webmail (on the
same/different host)? If you are, then the problem lies elswhere, and
you may need to check your firewall settings. Do you have iptables
running on the server? If you are connecting via SSL on the Outlook
clients, there could be (I'm just shooting in the dark here - not too
familiar with Outlook) with certificates from the old server being cached.
