That's ancient. I strongly suggest that you update, on security grounds as well as good general practice. > When an update of CSF is available an email with the update Cron info is sent > to the root address but this generate all time a Delivery Status Notification. Please use the "return" key occasionally. > The Exim Log says:** root@: mail domain "" is syntactically invalid Exim has gotten as far as trying to work with the address <root@> and cannot handle it thanks to the lack of a domain (the part after the '@'. For example in your address <[email protected]> the domain is "yahoo.it". I expect you have your firewall configured to send mail to "root" and are expecting Exim to add the domain part of the mail address. Look at your qualify_domain and primary_hostname main configuration options.
