# Set $domain to your domain name (no www)

# Set $docroot to the URL of the directory which contains your
# .htaccess file. Don't include trailing slash.

# to the webmaster. Use the $reportlevel variable to control when
# you receive these reports.

# 1 = send email only if the error's referer contains your domain name

# 2 = send email any time a 404 error is generated (useful for tracking
# broken links at other sites which link to you)
