When I do a:
[root@xxxx ~]# config show pop3s
pop3s=service
TCPPort=995
access=public
status=enabled
[root@xxxx ~]# config show pop3
pop3=service
TCPPort=110
access=public
status=enabled
So everything looks fine, but it does still not work form external IP's om my SME7.0. I also tried to change my router/firewall rules back to my old SME6.0 IP and I works fine from outside. So it is not the rules that is the problems I only change the IP address in the Nat&firewall rule.
I did enable POP3 Access for External sources from my Server-Manager.
