I'm not sure if you can do this withing cyrus, but if not, you could use 
a firewall (e.g. iptables) to restrict port 143/993 traffic to 
particular uid's:

   iptables -A my_chain -o ethX -m owner --uid-owner {USERNAME} 
--destination-port 143 -j ACCEPT

This might get onerous to manage if you have a lot of user accounts, though.
