This section concerns electronic mail servers or mail transfer agents (MTAs).

11.1. Sendmail

By default, the Sendmail mail transport agent (MTA) does not accept network connections from any host other than the local computer. To configure Sendmail as a server for other clients, edit /etc/mail/sendmail.mc and change the DAEMON_OPTIONS line to also listen on network devices, or comment out this option entirely using the dnl comment delimiter. Then install the sendmail-cf package and regenerate /etc/mail/sendmail.cf by running the following commands:
su -c 'yum install sendmail-cf' 
su -c 'make -C /etc/mail'
