Hi all
I'm blocked for incomming mail on port 25, so I have my mail backed-up and forwarded on port 26. This port is opened in the firewall and portforwarded on my external IP from port 26 to 25. 
Running ver. 6.0.1-01
Telnet gave the following:
External:
[root@kurt root]# telnet 82.143.221.140 26

Does this seem allright?
Anybody got a clue?
