Is there a way to reconfigure the name of the server given at install time with out sing everything?
What I want to do is to be able to go from courriel.mydomaine.com to courrier.mydomain.com.
In /etc/hostname, is sais courrier already and in hosts it says courrier.mydomaine.com already.
But in mailname it says courriel.mydomaine.com and during the install, that's what I used.
So How can I go about changing the name without having to reinstall everything and loose my users mailbox?
