Hello, I have the follwing error, when I try and send mail out of my  
machine (foucault) to someone on the same local domain, *.maths.mu.oz.au.
the mailhost here (mundoe) takes care of most mail (it handles my mail to  
other people not on the local domain), but gives me the error below when  
sending mail to mundoe.maths.mu.oz.au, or mundoe...

Can any kind person help me? The sys admin people here are pretty cool and  
will listen to good ideas, if the case is that something is not right on  
their side. If I can change something on my side, even better.
