Linux-mail failed with "name service error"

Linux-mail failed with "name service error"

And now for something quite different…. Some monitoring-scripts are  mailing to me, for example the backup-script (will do it later on in Grid Control….).  For a few nodes in the DMZ this didn’t work anymore. And actually I don’t want to know what is going on, but at the place I work there’s no Linux admin in the neighbourhood. So I can give it a try…

Appeared that the network-boys (no girls..) changed some configuration (mx-records or something like this).  Logging and “mailq” gave ‘Name service error’.
