* To permanently change your hostname from '''localhost.localdomain''', see this [http://www.labtestproject.com/using_linux/permanently_change_hostname_on_fedora article].

* Should your mail server hang up and stop working, you can most likely fix it with the following two scripts. Place them in the elevated directory. You must run these as root user :

{{Text|Text=/etc/init.d/courier-authlib start;

/etc/init.d/sendmail stop;

/etc/init.d/amavisd restart;

sa-update --no-gpg;}}

{{Text|Text=/etc/init.d/courier-authlib stop;

/etc/init.d/sendmail stop;

/etc/init.d/clamd.amavisd stop;

rm -f /var/spool/amavisd/clamd.sock;}}

{{Code|chown apache:users start.sh stop.sh

chmod 755 start.sh stop.sh}}</blockquote>
