Rewrite myhostname in /etc/postfix/main.cf in the install script
Rewrite myhostname in /etc/postfix/main.cf in the install script

This is necessary because the install script is also run on creating a

the new internal and external names; the hostname will be different in
this case and otherwise myhostname wouldn't be rewritten.
