Summary
    SELinux prevented /usr/sbin/sendmail.sendmail from using the terminal 0.

Detailed Description
    SELinux prevented /usr/sbin/sendmail.sendmail from using the terminal 0. In
    most cases daemons do not need to interact with the terminal, usually these
    avc messages can be ignored.  All of the confined daemons should have
    dontaudit rules around using the terminal.  Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this selinux-
    policy.  If you would like to allow all daemons to interact with the
    terminal, you can turn on the allow_daemons_use_tty boolean.

Allowing Access
    Changing the "allow_daemons_use_tty" boolean to true will allow this access:
    "setsebool -P allow_daemons_use_tty=1."

    The following command will allow this access:
    setsebool -P allow_daemons_use_tty=1
