How did you fix this problem please.

It would just be a matter of starting/restarting the lookup-domain service... you can start that in Webmin -> System -> Bootup and Shutdown. It would also get restarted upon bootup.

Well I've tried that but without success I had to delete mailque and than server started to act normaly.
