Nothing happening on port 25 with ne kolab installation

[Alexander Schröter]

Hi I have the following problem.

My New Installation won't recieve mail from the outside. I checked the 
litte box in the admin interface that says accept mail from the internet 
but nothing is happening.

A portscan shows me that port 25 has nothing happening and thats where 
the incoming mail should arrive at right?
So i figured let's take a look at that from the inside "netstat -l -n" 
which I guess looks good.

Can somebody help me figure this out?

  netstat -l -n
