I'm using fail2ban with CentOS 6.6. Something is causing fail2ban's alerts sent to root's mail to be rejected. Here's a clip from one of the error messages:

Check your /etc/fail2ban/jail.local /etc/fail2ban/jail.conf. You have to provide valid email addresses for dest= and sender= parameters in sendmail-whois or mail-whois actions for enabled jails.
