using postfix and dovecot on ubuntu 11.10

Hi,

I followed the linode library article on using postfix and dovecot on ubuntu 10.10, but apparently many things have changed (at least in dovecot) since that time. Now, whenever I try to start dovecot, it doesn't work. (or at least I assume it doesn't, because when I type service dovecot restart, it says):

restart: Unknown instance:

I found from another thread I had posted a while back that ubuntu 11.10 now uses dovecot 2.0, which has many different configuration changes. However, I'm not sure where to begin on fixing my config file (if that's even the problem).

Any help is appreciated.

Thanks,

-Michael.
