The mails will be written in my local postbox but if I check my mails form kmail ther are no mail in my kmail-inbox.

please help me with this problem. Sorry that I can't help you with that, but the funny thing is that we have the same problem here under SuSE 6.2. Maybe it's a kmail configuration problem. Maybe you just have to tell kmail to use /var/spool/mail/<username> as its inbox somewhere in the conf file. As we don't use kmail, I didn't try to solve the problem. BTW: This is OT here. Good luck!
