Hello, I'm pretty sure neither Perdition nor Dovecot can use SSL certificates based on which IP address the connection is received on, right? Of course firing up multiple instances of Perdition with separate config files binding them to their respective IPs is possible, but lacks a bit of elegance. And of course requires hacking/adding startup scripts, which in turn has the tendency to bite ones behind when it comes to installing security fix packages or entirely new versions. I'm not even sure if /var/run would be only place where multiple Perdition instances would step onto each others toes.
