[Dovecot] Feature-request: ip based access control (libwrap)

Is there plans to use libwrap Or is there already some kind of access control i have missed?? What i really want is a mechanism so i can say: If The request comes from "123.121.212.0" dont offer ssl and accept plain else demand ssl and no plain

I now have this (almost) in another imap server by xinetd and two ip addresses. I could solve this by iptables or access list on the router but i would prefer to have it in the software itself. (Sorry if this is a faq i have tried to check before i posted this)
