thank you very much for your explaination on this. You are absolutetly
right. For me this is not a problem since there are no private users
located at my box. If so I completly understand your hint and I
apreciate the time you took to give advice to us wannabees. I hope
Jehann will review his strategy and settings according to your post
which will make it in my wiki.
