Try to find the issue with the Mail/Message Flow Troubleshooter
under Exchange Management Console -> Tools
Run health check analyser as well

I found the issues,
one of the domain controller had a worng time that effected the Exchange server.
it is very wierd that only the internal emails does not arrive if this problem happens, external e-mail artive normaly.
i think it is becuase if the time is not right it does not authinticate correctly, and the internal connector requier authintication.

Any how thanks for the help.
