15.2 upgraded in place from 15.1. I can only telnet to port 25 on via localhost (127.0.0.1). Telnet to port 25 and others from on or off the server results in “connection denied”. The local firewall is not enabled and iptables shows no chains in effect.  
As a test added a secondary IP via yast and got the same issue.  
I am perplexed.
