Thank you for the reply - and yes, I can also lookup
www.malware.com.br on e.g.
http://www.kloth.net/services/nslookup.phpSo I now suspect that my Internet provider may be blocking for nslookup for this domain. I know this provider has done that for piratebay, but I have no idea why it would be blocking a server that is set up to help fighting spam.
I have now entered the IP address (66.79.164.43) of
www.malware.com.br directly in /etc/cron.daily/update_sanesecurity and this seems to work. But maybe a better solution would be to use e.g. opendns.org as nameserver? Any opinions on this? Or suggestions how to do it?
Kind regards,
Jesper
