I'm using tcpserver and there is no NAT between the smtp server and its dns 
resolver.
  
 I also tried to run the dns in the same smtp server but it didnt help.

Interesting thing is that when I reboot the smtp server, its works fine for a 
few minutes and then it start over again.

  So  I failed to get glues whether it is dns or something else.
