[Mageia-sysadm] [sysadmin-commits] [2116] Set myorigin (and mydomain + myhostname) for simple relay to be able to send emails from valstar without specifying domain

I have also noticed that on all servers except alamut, mails for root
are saved in /var/mail/postfix, with many errors that probably nobody
reads. So I think we should forward root emails on all servers to
root at mageia.org so that we receive them, and fix all errors (or silent
them if they are not important).
