very urgent problem with MailScanner + postfix

I had 2 servers this morning that I was looking at. One was freezing when
starting razor (couldn't contact the razor servers) while the other one
worked fine. On the one causing trouble, I wipe /.razor and /etc/razor,
downloaded and installed the latest razor distribution and everything is
working fine on both servers now.
There's probably a neat and quick way of refreshing all the server
information without reinstalling, but re-installing only took 5 minutes anyway.
