I setuped an Exim4 server to send mail for my website hosted on the same server. I configured my server to have a mydomain.com hostname. Sites and mails for site are working fine.
The problem I have is that system messages are also sent by mail. Before I used to find my user system messages in /var/log/username now they are sent to email@example.com.
How can I prevent this and keep logging message in /var/log for regular and root user ?
