dovecot - Nov 2011 - How to disable pop3 in version 2?

I'm about to bring up a new mail server running Ubuntu 11.10 with 
Dovecot 2.  I've been using 1.2 all along and there are a bunch more 
config files in 2.  In 1.2 I just edited the protocols statement but I 
can't find one in version 2.  Is there a way to disable pop3 or do I 
just firewall the ports?

And a related question, I've been using imaps on port 993 but I hear 
that's not the best solution anymore, I should be using imap with 
STARTTLS?  How do I disable imaps?

Thanks,

In the example dovecot.conf there's a protocols setting. If you don't
see any, you can just add your own wherever. "protocols=imap" should
work.

Well, http://wiki2.dovecot.org/SSL explains this more. I don't think you
really need to disable imaps, but if you want to, you can do it with:

service imap-login {
  inet_listener imaps {
    port = 0
  }
}
