hello,

I've installed the kubuntu-desktop on ubuntu hardy. This automatically installed postfix. I always thought that running a mailserver was a potential security risk and that if you install (K)ubuntu no such services would be running by default. Further more I do not understand what's the use of a mailserver in connection with a desktop. I only need a mailclient (seamonkey in my case) to read my mail.

Eniel,

It is not a problem as postfix should be listening on loopback address, you can verify it by running "sudo netstat -pant|grep -i master". Check for entry like this.

tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2448/master

Listening on loopback address means that external machines can't connect to this service and is for internal use only.

Hope this helps

Thanks for the answer. It works as you said, so I know the configuration is safe.
Still I'm a little astonished that a mailserver gets installed by default with kubuntu desktop since I would expect a normal desktop user to only need a mail client
