are you sure there isn't a firewall in place blocking port 8020? e.g. iptables on the local machines? if you do telnet localhost 8020 do you make a connection? if you use lsof and/or netstat can you see the port open? if you have root access you can try turning off the firewall with iptables -F to see if things work without firewall rules. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good.
