As do I..

But the system still sends mail to roots alias AS root, which means it  
doesn't get masqueraded and thus is rejected by the mail server  
because root at somebox.somedomain.com doesn't exist as far as the server  
is concerned, however root at somedomain.com it would be perfectly happy  
to accept..
