Postfix configuration was not changed. If you need to make changes, edit

/etc/postfix/main.cf (and others) as needed. To view Postfix configuration

values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

Affecting to postfix.
Is it the default configuration file or a customized one ?

Thanks
