You can just refer to the Postfix article ( http://wiki.centos.org/HowTos/postfix ) which says: "First we need to tell our system to use postfix as the MTA rather than the default sendmail. To do this, run the system-switch-mail command and select postfix as the MTA. This will install the postfix service and set it to start automatically at runlevels 3, 4, and 5." Akemi
