Is there a way I can have something like the following setup:

192.168.0.2 port 110/143, with no starttls/ssl 192.168.0.3 port 110,995/143,993 with starttls/ssl 192.168.0.4 port 110,995/143,993 with starttls/ssl

I am looking to setup dovecot so that some IPs will run without any notion of SSL whereas other IPs will run with with ssl/starttls available, each with its own certs
