I followed http://wiki2.dovecot.org/LoginProcess#TCP_wrappers_support
and "man 5 hosts.deny"

- to allow all clients and deny a specific address

   /etc/hosts.deny
   imap: 192.0.2.143

- to deny all clients and allow a specific address

   /etc/hosts.deny
   imap: *

   /etc/hosts.allow
   imap: 192.0.2.143
