hi all i discovered that just after installation of MDK 9.0, the "newaliases" command doesn't work. it points to a file /etc/alternatives/mta-newaliases which doesn't exist.
un- and reinstalling the package postfix resolves the problem. the symlinks in /etc/alternatives are then created properly.... and there are even more there after that. must be a bug in the mandrake install utility (i don't remember it's name.. drak... xyz hmmm ?) spiderboy
