[PERDITION-USERS] STARTTLS ip based

Hello perdition users! I really appreciate Perdition, works great also in large environment! I see that Perdition supports STARTTLS/STLS to manage secure connections. In my network I would like separate "good" ips and "bad" ips, where "good" can establish a clear connection (tls_listen), and "bad" must starttls (tls_listen_force), all on the same perdition server. Is this possible? It would be very useful for me if ssl_mode could be user based (for instance set on LDAP profile of the account). Otherwise, it could be very useful a behaviour like Postfix: local networks can connect without encryption, and other must use STARTTLS. Thanks a lots Best Regards Marco
