Configure Logwatch Link
Once you have installed Logwatch, you will need to configure it to email you the reports it generates. You are encouraged to look through the entire configuration, but you may safely use Logwatch after editing the lines below.
File: /usr/share/logwatch/default.conf/logwatch.conf
LINE 35
Output = mail
LINE 37
Format = html
LINE 44
MailTo = <validemail >@mydomain.com
Add this line
MailFrom = logwatch@mydomain.com
These directives tell Logwatch to email you reports in an HTML format. The MailTo and MailFrom directives should be valid email addresses.
Issue the following command to test your logwatch installation:
logwatch
Once you have issued this command, you will need to check your email to make sure that logwatch is working. Be sure to check your spam folder as these emails may be seen as spam.
