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?

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
  }
}
