Technical Details

what runs on :3206

IronMail POP Proxy is registered on port :3206 over tcp and udp to Mike Hudack. We don't have a technical write-up for it beyond the IANA registry entry.

In nmap's internet-wide scan data this port is never observed open, so if it's open on your network it's more likely a custom or misconfigured service than the registered one.
